Two-Sample Assuming Unequal Variances for the Data File Golf (Chapter 10) using the video How to Add Excel’s Data Analysis ToolPak (Links to an external site.) for assistance.
In a managerial report, use the methods of hypothesis testing to
Formulate and present the rationale for a hypothesis test that Par could use to compare the driving distances of the current and new golf balls.
Analyze the data to provide the hypothesis testing conclusion. What is the p-value for your test? What is your recommendation for Par, Inc.?
Provide descriptive statistical summaries of the data for each model.
Explain what the 95% confidence interval is for the population mean driving distance of each model, and explain what the 95% confidence interval is for the difference between the means of the two populations.
Discuss whether you see a need for larger sample sizes and more testing with the golf balls.
States has a high level of dependence on PNT systems which factors into this motivation due to it being a prime target of deterrence strategies. An Inside GNSS article quoted former Chief of Staff of the Air Force, General Norton Schwartz, “Our dependency on the Global Positioning System has also created certain vulnerabilities that our adversaries can exploit through jamming and other tactical denial techniques.” This vulnerability provides the means for China to take an upper hand in competition and conflict with the United States. According to Phillip C. Saunders in Joint Force Quarterly, “One China expert suggested that the key messages are that the United States could not expect to dominate space alone.” Much like how the United States has a high dependence on space based technologies, China has a growing dependence on the very same technologies. This need presents a growing motivation for the expansion of programs. While there is a growing dependence on these technologies, it is not close to the level of dependence of the United States. China is currently dependent on many American owned assets in space. This provides additional incentive to further their own programs to become technologically independent. According to the testimony of Dr. Ashley J. Tellis, China’s greatest advantage is not the American dependence on the technology alone, but rather the difference between American dependence and Chinese dependence. Counterspace programs both enhance the level of security for China. Counterspace weapons allow for China for diversify and expand its military capabilities. This further modernizes China’s military while also giving an additional outlet of both offensive and defensive strategy. Bruce MacDonald references that counter space is relevant to China’s national security goals. The security dilemma can fundamentally apply here since the United States is the largest threat China could face. Such theory of escalation is expanded on by James Finch. Space is one area of potential for major economic growth. Such can be seen with the success of companies like SpaceX and Boeing. Establishing a stronger state owned space presence will establish a foundation for Chinese private companies to establish a commercial market. An expanding counterspace presence will allow the Chinese to protect commercial interests set up by their space efforts. Thus sets up a strong potential for motivation of expanding counter space programs. Implications of Counter space Threats:>GET ANSWER
