Researchers determine that 60 Puffs tissues is the average number of tissues used during a cold. Suppose a random sample of 100 Puffs users yielded the following data on the number of tissues used during a cold: = 52 and s = 22 . Using the sample information provided, the value of the test statistic is:
 a. t = (52 - 60) / 22 c. t = (52 - 60) / (22 / 1002)
  b. t = (52 - 60) / (22 / 100) d. t = (52 - 60) / (22 / 10)

Question 2

We can use the Friedman test to determine whether a difference exists between two populations. However, if we want to determine whether one population location is larger than another, we must use the sign test.
  Indicate whether the statement is true or false
