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: X-bar = 52, s = 22. Using the sample information provided, calculate the value of the test statistic.

a. t = -0.3636

b. t = -36.3636

c. t = -3636.3636

d. t = -3.6364

Suppose the alternative we wanted to test was H1: Mean < 60. State the correct rejection for a = 0.05.

a. Reject H0 if t > 1.6604

b. Reject H0 if t < -1.6604

c. Reject H0 if t > 1.9842 or Z < - 1.9842

d. Reject H0 if t < -1.9842
