Note that a normal probability plot and boxplot of the data indicate that the differences are approximately normally distributed with no outliers. Choose the correct null and alternative hypotheses below. Let d_i = Y_i - X_i. A. H_0: mu_d = 0 H_1: mu_d notequalto 0 B. H_0: mu_d = 0 H_1: mu_d > 0 C. H_0: mu_d 0 D. H_0: mu_d > 0 H_1: mu_d
