How many tissues should the Kimberly Clark Corporation package of Kleenex contain? Researchers determined that 60 tissues is the mean 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: X= 52, S= 22. Suppose the test statistic does fall in the rejection region at = 0.05.

You have created a 95% confidence interval for with the result 10 K K 15. What decision will you make if you test H0: = 16 versus H1: J 16 at = 0.05?
