veights. Under the Bld months. A journal reported that an airline conducted a study to estimate average passenger plus carry-on weights. They found an average summer weight of 183 pounds and a winter average of 190 pounds. Suppose that each of these estimates was based on a random sample of 100 passengers and that the sample standard deviations were 16 pounds for che summer weights and 22 pounds for the winter weights. A USE SALT (a) Construct a 95% confidence interval for the mean summer weight (including carry-on luggage) of this airline's passengers. (Use technology to calculate the critical value. Round your answers to three decimal places.) Interpret a 95% confidence interval for the mean summer weight (including carry-on luggage) of this airline's passengers. O There is a 95% chance that the true mean summer weight (including carry-on luggage) of this airline's passengers is between these two values. O There is a 95% chance that the true mean summer weight (including carry-on luggage) of this airline's passengers is one of these two values. O There is a 95% chance that the true mean summer weight (including carry-on luggage) of this airline's passengers is directly in the middle of these two values. O We are 95% confident that the true mean summer weight (including carry-on luggage) of this airline's passengers is between these two values. O We are 95% confident that the true mean summer weight (including carry-on luggage) of this airline's passengers is directly in the middle of these two values. (b) Construct a 95% confidence interval for the mean winter weight (including carry-on luggage) of this airline's passengers. (Use technology to calculate the critical value. Round your answers to three decimal places.) Interpret a 95% confidence interval for the mean winter weight (including carry-on luggage) of this airline's passengers. 10:28 PM
