HI6007 STATISTICS AND RESEARCH METHODS FOR BUSINESS DECISION MAKING
Please read below information carefully and respond all questions listed.
The planet may be threatened by climate change due to unsustainable activities, possibly caused by
burning fossil fuels (petroleum, natural gas and coal) that produce carbon dioxide (CO2). The table
stored in file CO2 EMISSIONS.XLSX (in the course website) lists the top 15 producers of CO2 (millions
of metric tonnes) from fossil fuels in 2009 and 2013. Using this data, answer the questions below.
(a) Use an appropriate graphical technique to compare the amount of CO2 emissions (in
millions of metric tonnes) in 2009 and 2013, broken down by the producer countries.
(b) Use an appropriate graphical technique to compare the percentage value of the amount
of CO2 emissions (in %) in 2009 and 2013, broken down by the producer countries.
(c) Comment your observations in parts (a) and (b). (2 marks)

Because inflation reduces the purchasing power of the dollar, investors seek investments that will
provide protection against inflation; that is, investments that will provide higher returns when
inflation is higher. It is frequently stated that ordinary shares provide just such a hedge against
inflation. The annual Australian inflation rate (as measured by percentage changes in the consumer
price index) and the annual All-Ordinaries Index from 1995 to 2015 are stored in file INFLATION.XLSX
(in the course website).
Using EXCEL, answer below questions:
a. Using an appropriate graphical descriptive measure (relevant for time series data) describe the
two variables. (1 mark)
b. Use an appropriate plot to investigate the relationship between RATE OF INFLATION and ALLORDINARIES INDEX. Briefly explain the selection of each variable on the X and Y axes and why?
c. Prepare a numerical summary report about the data on the two variables by including the
summary measures, mean, median, range, variance, standard deviation, and coefficient of
variation, smallest and largest values, and the three quartiles, for each variable.
d. Calculate the coefficient of correlation (r) between RATE OF
INFLATION and ALL-ORDINARIES INDEX. Then, interpret it. (2 marks)
e. Estimate a simple linear regression model and present the estimated linear equation. Then,
interpret the coefficient estimates of the linear model. (4 marks)
f. Determine the coefficient of determination R2 and interpret it. (2 marks)

Presentation Movies as vehicle of Mass Communication Film correspondence might be considered as a social procedure whereby a transmitted sign is gotten essentially through visual receptors (and, frequently, solid receptors) and is then treated as a message from which substance or significance is surmised. Film, as a representative structure, is a procedure of correspondence that utilizes film, the medium, with its innovation of optics, emulsions, and cameras, to create a bit of celluloid with a variable-thickness silver nitrate surface. It is man who makes film correspondence. This definition recommends that a bit of film, all by itself, is pointless that significance exists just in an exceptional social and subjective connection between a producer and a watcher. This relationship happens when a watcher treats a film not as minor sign activating perceptual mindfulness and natural reactions, yet as message units that have been assembled deliberately and from which importance might be construed. Film is maybe the standard of all works of art, most prominent and most open, particularly in India, a nation which delivers most number of movies in a year contrasted with some other nation (excepting Hollywood, maybe), and a nation where we have an enormous base of film opening up to the world. Film, more than some other workmanship, has the ability to impact individuals. Hence, it is critical to see how the nation, its kin and its goals are spoken to in the film created in the nation. Film as a mechanism of mass correspondence can be seen at various levels, filling various needs. It very well may be a fine art, a stimulation, a social archive or a social study. Film can be these and simultaneously be a way to something different – a mirror unto our lives, demonstrating us precisely how we work as society. Standard Vs Alternative Cinema Mainstream movies can best be characterized as business films that are made by real amusement studios or organizations that are claimed by universal media aggregates. In view of better financing, these movies can manage the cost of progressively costly on-screen characters, wide discharges or constrained discharges, and are sold at well known retail locations. This has turned out to be known as the studio framework. Movies made by significant studios or organizations that are not possessed by a media combination however are disseminated by an organization claimed by a media aggregate are likewise viewed as standard and are frequently alluded to as standard autonomous movies. As a standard medium (film needs cash to be delivered. In this manner, it must speak to the standard group of spectators, who will pay in the cinematic world) film must, as a matter of first importance, advance to the standard crowd. The meaning of standard differs from society to society, from culture to culture. Comprehensively, it means speaking to the pervasive mentalities, qualities, and practices of a general public or gathering, for instance, standard ethical quality. A social build, when applied to workmanship, standard may mean something that is accessible to the overall population, or something that has connections to corporate or business elements. Sexuality in Hindi standard movies alludes to the introduction in films of sexuality or sensuality and sex acts, including love scenes. Sensual scenes have been displayed in movies since the quiet period of cinematography. Numerous entertainers and on-screen characters have uncovered at any rate portions of their bodies or dressed and acted in manners considered explicitly provocative by contemporary gauges sooner or later in their vocations. A few movies containing simulated intercourses have been condemned by religious gatherings or restricted by Govt. or then again both. Sexuality in film has been displayed in numerous classifications of film; while in certain sorts sexuality is seldom portrayed. Sex in movies can be recognized to an explicit film and furthermore from nakedness in film, bareness can be exhibited in a sexualized setting, for instance bareness in naturalism would ordinarily be viewed as non-sexual. In India, media outlets is a significant piece of present day India and is expressive of Indian culture when all is said in done. Generally Indian movies have come up short on the straight to the point portrayal of sex; up to this point, notwithstanding kissing scenes were viewed as unthinkable. Then again assault scenes or demonstrating rape were portrayed straightforwardly. Right now some Indian states show delicate center sexual scenes and bareness in movies, while different zones don't. Standard movies are still to a great extent cooked for the majority of India, anyway outside movies containing sexuality are viewed by Indians as a result of a similar procedure of glamorization of film stimulation that happened in Hollywood, Indian film, chiefly Hindi-speaking Bollywood industry is likewise starting to include sexual suggestions. A Brief History of Bollywood Sex and Romance Bollywood works of art can't be beaten for their obvious sentimental pressure, where personal contacting was supplanted with the idyllic, affable allusion of hot downpour and wet garments. Indians are so held about what occurs between consenting grown-ups, considering India is the second most crowded nation on the planet. Somehow or another, be that as it may, Hindi movie producers have turned out to be progressively loose in their frames of mind, as more youthful, Western-affected ages become an adult and cause a ripple effect in an industry based on custom. Beforehand inconspicuous "taboos" like pre-marriage sex, onscreen nakedness and even spouse swapping have inquisitively been passed by the Central Board of Film Certification, the severe guard dog likeness the MPAA that has filled in as an edit since the mid '50s. Assembled beneath is a glance at the milestone minutes and patterns that have cocked eyebrows through Bollywood history. Bollywood in the 70's and 80's was getting to be westernized. In those days the presence of a plain white brassiere spoke to the taboo idea of onscreen toplessness. An entertainer wearing only her over-the-shoulder stone holder who flipped off the lights, for example, would suggest that she would before long be demonstrating her bosoms to her darling. In the event that anybody understood the intensity of such dressed titillation, it was Raj Kapoor, whose movies started to stretch the limits late in his directorial vocation. His unmatched 1973 high schooler sentiment "Bobby" made a medium-term stick up vibe of Dimple Kapadia when she showed up in a two-piece, and 1978′s "Satyam, Shivam, Sundaram" (which confronted a difficult task with the control load up, and was censured by some as being exploitative) saw Zeenat Aman in a scarcely there sari that opposed material science by remaining on. His last film, 1985′s "Smash Teri Ganga Mali" brought about additional debate when 16-year-old star Mandakini showed up washing in a cascade, wearing just a transparent white. Today, swimsuit darlings are unmistakably increasingly predominant in Bollywood culture, and 2000′s "Hera Pheri" even portrayed male sunbathers in two-pieces, mixed up as young ladies from a separation by the film's hero. Up until the '50s, if Bollywood stars needed to express love or even desire onscreen, fastening each other's hands and gazing longingly was about as ribald as it got. Embracing and light face touching turned into the following jump over the accompanying three decades, however it wasn't until the '90s that kissing was truly recognized, not to mention done. A lady may lean in for lip administration, however would bashfully flee before the arrangement was fixed, or else the genuine demonstration would be shrouded by a cover at the time previously. While this, as well, is evolving today (whiz on-screen character Aamir Khan even has a kissing proviso placed in his co-stars' agreements; in the event that they won't kiss him, they can't act inverse him), puckering up can in any case be hostile. Padmini Kolhapure stood out as truly newsworthy when she only gave Prince Charles a peck on the cheek, and after Aishwarya Rai got private with Hrithik Roshan in 2006′s "Dhoom 2," indecency cases were recorded. "Thing numbers," or profoundly sexualized, playful Bollywood melodies with interesting verses and movement, started springing up in the late '80s and particularly during the '90s. Intended to stimulate, enthusiasm for the business films they show up in, thing numbers are remain solitary works of art with no importance to their motion pictures' plots, including either appearance appearances from celebrated stars — or all the more commonly, "thing young ladies." Here, externalization ought not to be mistaken for the hot artists in progressively uncovering garments have turned into somewhat less criticized today, as some have utilized the feature as a springboard into driving jobs. Among the approved performers, at that point, comes the thought of "skin appear," what India vaguely calls any idea of on-screen characters and even entertainers now, who are eager to display more than what the traditionalist models manage. Dare-uncovered entertainers like Bipasha Basu in 'Jism' and the questionably blunt Mallika Sherawat in 'Murder' have accomplished reputation for their sparsely clad limit pushing alone. Elective Lifestyles Bollywood plots have positively advanced, less fixated on masterminded relationships and more on youthful urbanites dating and clubbing. Be that as it may, these are still gradual steps contrasted with what has been familiar with in Western culture. India still remains closeted in changing sexual inclinations. In 2003 "Kal No Naa Ho" treated homosexuality with droll, and the ongoing "Dostana" concerns two fakers in a similar vein, yet little walks have been made to bring genuineness and receptiveness to the film. In 2005 "My Brother… Nikhil" unobtrusively carried attention to the AIDS emergency, yet it never could have existed without the massively questionable 1996 arrival of Deepa Mehta's "Fire," the primary Bollywood film to portray homosexuality. At the point when the last film opened, there were irate dissents and across the board vandalism — cinemas demonstrating the film were savagely raged, with windows crushed and notices consumed. While it's difficult to accept such bigotry over so little could exist in the cutting edge period. This too should be in any way thought about that "Kabhi Alvida Na Kehna" (which caused a ripple effect for its dealings in infidelity an>GET ANSWER
