Researchers at a tissue supply company determined that 60 tissues is the mean number of tissues used during a cold. Suppose a random sample of 25 Kleenex tissues users yielded the following data on the number of tissues used during a cold: X¯ = 52, S = 22. Suppose the alternative you want to test is H1 : µ < 60. State the correct rejection region for α = 0.05.

a.Reject H0 if tSTAT < −1.7109

b.Reject H0 if tSTAT < −1.6766

c.Reject H0 if tSTAT > 1.6766

d.Reject H0 if tSTAT > 1.7109

Kimberly Clark Corporation’s Kleenex packages contain 60 tissues because their researchers determined that 60 tissues is the average number of tissues used during a cold. There is concern, though, that the tissue counting machine is not working properly. Suppose a random sample of 91 Kleenex packages contains an average of 52 tissues with a standard deviation of 22 tissues. Determine whether the tissue counting machine needs to be recalibrate to ensure the Kleenex packages contain an average of 60 tissues....

Researchers claim that 60 tissues is the average number of tissues a person uses during the course of a cold. The company that makes Kleenex brand tissues thinks that the average person doesn’t need as many for a cold if their tissues are used. What are their null and alternative hypotheses? H0:  = 60 vs. HA: 60 H0:  < 60 vs. HA: 60 H0:  = 60 vs. HA: <6 H0:   60 vs. HA: <60
