4. A random sample of 1,557 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 3.10, and the sample standard deviation was 1.24. Test at the 1% significance level, against a two-sided alternative, the null hypothesis that the population mean is 3.0.

9.17(under 9.3) A random sample of 1562 undergraduates enrolled in management ethics courses were asked to respond on a scale from 1 (strongly disagree) to 7 (strongly agree) to this proposition: Senior corporate executives are interested in social justice. The sample mean response was 4.27, and the sample standard deviation was 1.32. Test at the 1% level, against a two sided alternative, the null hypothesis that the population mean is 4.

/courses/1631958/q 2791378/take D Question 5 12 pts Pulse Rates of Men. A simple random sample of 40 men results in a standard deviation of 10.3 beats per minute (based on the data set provided). The normal range of pulse rates of adults is typically given as 60 to 100 beats per minute. If the range rule of thumb is applied to that normal range, the result is a standard deviation of 10 beats per minute. Use the sample results with...
