In order to determine the average weight of carry-on luggage by passengers in airplanes, a sample of 36 pieces of carry-on luggage was collected and weighed. The average weight was 19 pounds. Assume that we know the standard deviation of the population to be 8.5 pounds. What is the Margin of Error (MOE) if a 97% confidence interval is desired?
What is a 97% confidence interval (CI) estimate for the mean weight of the carry-on luggage?

What is the Margin of Error (MOE) if a 95% confidence interval is desired?

What is a 95% confidence interval (CI) estimate for the mean weight of the carry-on luggage?

Discuss why the 97% and 95% confidence intervals are different.
How large the sample must be in order to obtain 97% confidence interval with margin of error equal to 3.0 lb.
