How many tissues should the Kimberly Clark Corporation package of Kleenex 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: $\bar { X }$ = 52,s = 22.
- Suppose the test statistic does fall in the rejection region at $\alpha$= 0.05.Which of the following conclusion is correct?
A) At $\alpha$ = 0.05, there is not sufficient evidence to conclude that the average number of tissues used during a cold is 60 tissues.
B) At $\alpha$ = 0.05, there is sufficient evidence to conclude that the average number of tissues used during a cold is 60 tissues.
C) At $\alpha$ = 0.10, there is sufficient evidence to conclude that the average number of tissues used during a cold is not 60 tissues.
D) At $\alpha$ = 0.05, there is not sufficient evidence to conclude that the average number of tissues used during a cold is not 60 tissues.
