0 : 1 2 H a : 1 2 and report the p -value. p -value = (to 3 decimals) At a 0.05 level of significance
what is your conclusion? I. Reject H 0 . There is not sufficient evidence to conclude that the
mean satisfaction scores differ for the two retailers. II. Do not reject H 0 . There is not sufficient
evidence to conclude that the mean satisfaction scores differ for the two retailers. III. Reject H 0 .
