A random sample of 1589 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 5.14, and the sample standard deviation was 1.34. a. Test at the 5% significance level, against a two-sided alternative, the null hypothesis that the population mean is 5. b. Find the probability of a 5%-level test not rejecting the null hypothesis when the true mean response is 4.85. Click the icon to view the standard normal distribution table. A. Ho: 5 H: <5 C. Ho: 5 H: >5 A. Reject Ho if For this test at the significance level & with sample mean x, hypothesized mean , population standard deviation o, sample size n, and za or Z/2, what is the form of the decision rule? x-Ho 0/n B. Reject H if x - Ho 0/n C. Reject H if x - Ho oln Za x-Ho 0/n Determine the value for Za, Za, or Z/2 as appropriate for this test. >Zal2 A random sample of 1589 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.
