Which option is correct

ses 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 a = 0.05 Which of the following conclusion is correct? Select one a. At a = 0.05, there is sufficient evidence to conclude that the mean number of tissues used during a cold is 60 tissues b. At a = 0.05, there is insufficient evidence to conclude that the mean number of tissues used during a cold is not 60 tissues c. At a = 0. 10, there is sufficient evidence to conclude that the mean number of tissues used during a cold is not 60 tissues. O d. At a = 0.05, there is not sufficient evidence to conclude that the mean number of tissues used during a cold is 60 tissues Next page
