A professional tennis player has a serve-return rate of p = 0.71. A random sample of 55 serve returns is selected. Which of the following is the mean of the sampling distribution of p hat ? Mu Subscript p hat Baseline = p = 0.71
Mu Subscript p hat Baseline = n p = 55 (0.71) = 39.05
Mu Subscript p hat Baseline = 1 minus p = 1 minus 0.71 = 0.29
Mu Subscript p hat Baseline = n (1 minus p) = 55 (1 minus 0.71) = 15.95
