Question: How many tissues should a package of tissues contain? Researchers determined that 68 tissues is the avg. number of tissues used during a cold. Suppose a random sample of 100 tissues users yielded the following data of the number of tissues used during a cold:
x-bar = 63, s = 17
Suppose the alternative we wanted to test was Ha: µ < 68. State the correct rejection region for α = .05.
