The Nerо Mаtch Cоmpаny sells mаtchbоxes that are supposed to have an average of 40 matches per box, with σ=9. A random sample of 94 Nero matchboxes shows the mean number of matches per box to be 38.1. Using α=0.01 , test the claim that the number of matches per box is less than 40. Match the claim, hypotheses, and significance level with their values for this problem. Answers may be used more than once or not at all.
