Question

How many tissues should a package of tissues contain? Researchers have determined that a person uses an average of 61 tissues during a cold. Suppose a random sample of 2500 people yielded the following data on the number of tissues used during a cold: Suppose the corresponding test statistic falls in the rejection region at What is the correct conclusion? Select one: a. At α = .05, reject H0. b. At α = .05, accept Ha. c. At α = .10, reject Ha. d. At α = .10, reject H0.

Answer 1

If the corresponding test statistic falls in the rejection region at α = .05, then we reject the reject H0 at α = .05.

a. At α = .05, reject H0

If the corresponding test statistic falls in the rejection region at α = .10, then we reject the reject H0 at α = .10.

d. At α = .10, reject H0
