The ages (in years) of patrons at a large nightclub has a distribution that is skewed to the right with mean μ and standard deviation σ = 3.0. Suppose 36 patrons are randomly selected and the sample mean age x ̄ = 24.1. We would like to test H0 : μ = 25 versus Ha : μ < 25="" at="" the="" α="0.05" significance="" level.="" which="" of="" the="" following="" is/are="">
(A) The rejection region goes from −∞ to −1.96(B) The p−value for this test is 0.0718(C) μ is significantly less than 25(D) We can not do inference for μ since we are sampling from a non-normal distribution
