Question

How many Kleenex should the Kimberly Clark Corporation package of tissues contain? Researchers determined that 60 tissues is the average number of tissues used during a cold. Suppose a random sample of 100 Kleenex users yielded the following data on the number of tissues used during a cold: Xbar = 52, s = 22. Suppose the test statistic does fall in the rejection region at = 0.05. Which of the following conclusions is correct?

A- At = 0.05, there is not sufficient evidence to conclude that the average number of tissues used during a cold is not 60 tissues.

B- At = 0.05, there is not sufficient evidence to conclude that the average number of tissues used during a cold is 60 tissues.

C-At = 0.05, there is sufficient evidence to conclude that the average number of tissues used during a cold is 60 tissues.

D-At = 0.10, there is sufficient evidence to conclude that the average number of tissues used during a cold is not 60 tissues.

E-None of the above are correct.

Explanation / Answer

Given that the test statistic fall in the rejection region. So,

At = 0.05, there is sufficient evidence to conclude that the average number of tissues used during a cold is not 60 tissues. Since this is not present in any of the options.

Option E is correct.
