Researchers Determine That 60 Puffs Tissues Is the Average Number $\bar { x }$

question 58

Multiple Choice

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: $\bar { x }$ = 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)
