Researchers Determine That 60 Kleenex Tissues Is the Average Number

Multiple Choice

Researchers determine that 60 Kleenex tissues is the average number of tissues used during a cold. Suppose a random sample of 100 Kleenex users yielded the following statistics 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
B) t = (52 - 60) /(22/100)
C) t = (52 - 60) /(22/100²)
D) t = (52 - 60) /(22/10)
E) t = (52 - 60) /(22/10²)
