1) 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: x = 51, s = 25. Suppose the corresponding test statistic falls in the rejection region at a = .05. What is the correct conclusion? A) At a .10, reject Ha. C) At a = .05, accept Ha. B) At a .10, reject Ho- D) At a .05, reject Ho.
