This test has ve questions. Each question has a separate tab at the bottom of the page. Question 1 This question has two pages with 4 parts. A random sample of 100 U.S. college students had a mean age of 22.68 years. Assume the population standard deviation is a = 4.74 years. 1) In constructing a condence interval for the mean age of students would you use the normal distribution or the t-distribution to compute the critical value for the margin of error computation? Explain your reasoning below. 2) Construct a 99% confidence interval for the mean age of students using the critical value method. You will need to compute the following. Put your answers in the yellow cells. Be sure to include a one-sentence interpretation of your results. Critical Z or T Standard Error Margin of Error lower bound upper bound MUM Interpretation
