How many tissues should a package of tissues contain? Researchers determined that 68 tissues is the average number of tissues used during a cold. Suppose a random sample of 100 tissue users yielded the following data on the number of tissues used during a cold: x=63, s=17. Suppose the alternative we wanted to test was Ha: μ < 68. State the correct rejection region for &=.05. Select one: A. Reject H0 if z < -1.645. B. Reject H0 if z > 1.96 or z < -1.96. C. Reject H0 if z < -1.96. D. Reject H0 if z > 1.645.
