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: Suppose the test statistic does fall in the rejection region at = 0.05.Which of the following decision is correct?
A)At = 0.05, you do not reject
B)At = 0.05, you reject
C)At = 0.05, you do not reject
D)At = 0.10, you do not reject

Since the test statistic falls in the rejection region at a significance level of 0.05, we reject the null hypothesis that the mean number of tissues used during a cold is 60. Therefore, the packaging of Kleenex by Kimberly Clark Corporation should contain more than 60 tissues. Since the test statistic falls in the rejection region, we reject the null hypothesis. The null hypothesis, in this case, is that the mean number of tissues used during a cold for Kleenex users is 60. Therefore, the alternative hypothesis is that the mean is not 60.
