In the 2015 AFC championship game, there was a charge the New England Patriots underinflated their footballs for an advantage. The balls should be inflated to between 12.5 and 13.5 pounds per square inch. The accompanying data consists of eleven of the twenty-two measurements on the Patriots' footballs. Complete parts a and b 10.85 11.95 11.00 10.95 11.35 10.90 10.50 11.10 11.85 11.55 10.70 O a. Test the hypothesis that the population mean is less than 12.5 psi using a significance level of 0.05. State dearly whether the Patriots' fotbalis are underinflated or not. Assume the conditions for a hypothesis test are satisfied, Determine the null and alternative hypotheses. Choose the correct answer below. OA Hi > 12.5 Hi us 12.5 O8. Hy p< 12.5 H2 12.5 C. H 12.5 H e12.5 OD.
