A random sample of 1532 undergraduates enrolled in management ethics courses was asked to respond on a scale from 1 (strongly disagree) to 7 (strongly agree) to the proposition that senior corporate executives are interested in social justice. The sample mean response was 4.06, and the sample standard deviation was 1.39. a. Test at the 5% signicance level, against a two-sided alternative, the null hypothesis that the population mean is 4. b. Find the probability of a 5%-level test not rejecting the null hypothesis when the true mean response is 3.85. :4] Click the icon to view the standard normal distribution table. m a.
