question 194

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)
