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)
