1) A. Generate 50 random samples of n=30 from a normal population with µ=69 and σ=3.Construct 90% confidence intervals for each of the 50 samples. These confidence intervals will appear in the output session window. Copy/paste them into your excel spread sheet and print the spreadsheets to turn in. B. Look at the confidence intervals. How many of your intervals failed to correctly estimate µ? How many of your intervals actually did contain µ? C. What percentage of your intervals contained µ? D. Based on the confidence level used in this example, what percentage of the intervals did you expect to contain µ? E. How does your actual percentage compare with the percentage you expected based on the confidence level? How has this experiment helped you understand what level of confidence means? Explain.
