For math problems, type out equations to receive partial credit in the case of wrong answer.

  1. Complete the cumulative frequency table below:
    X f p % cf c%
    5 2
    4 1
    3 4
    2 0
    1 2
  2. Given the following set of scores: 3, 4, 6, 7, 8, 8, 8, 3, 4, 1, 1, 2, and 5
    a. Mean =
    b. Median =
    c. Mode =
    d. Range=

  4. Watch the following video (https://www.youtube.com/watch?v=5D1gV37bKXY).
    a) What are the chances of Bill not being chosen 3 nights in a row?
    b) What are the chances that Bill is not chosen 12 nights in a row?
    c) What is the probability that most research use as their criteria for deciding whether or not an outcomes happens by random chance?
  5. Watch the following video (https://www.youtube.com/watch?v=MRqtXL2WX2M). Then, answer the questions below.
    a) What does a low standard deviation mean?

b) What does a high standard deviation mean?

c) What is the “68-95-99.7 rule?” and how could it be useful?

  1. Watch the following video (https://www.youtube.com/watch?v=jvoxEYmQHNM&index=6&list=PLo9NtuLffoEEuBmo-2BwHut0kzWvUYXMU). Then, answer the questions below.
    a) The more subjects in a sample at a time, the __________the distribution of the measure will be to a normal distribution. b) The bigger the sample size, the closer the mean of the sample gets to the _____________________________.
  2. You have a patch of 120 clovers. 13 of the clovers are 4-leaf clovers and the rest are 3-leaf clovers. What is the probability that you would randomly select a 4-leaf clover?
  3. At the end of every rainbow there is either a pot of gold or a pot of honey. If you randomly selected a rainbow, only 6% of the time would there be a pot of gold. How many rainbows out of 100 rainbows total would you expect have a pot of honey? (read carefully)
