Data from the Office for National Statistics show that the mean age at which men in Great Britain get married was 32.0. A news reporter noted that this represents a continuation of the trend of waiting until a later age to wed. A new sample of 47 recently wed British men provided their age at the time of marriage. These data are contained in the Excel Online file below. Construct a spreadsheet to answer the following questions. X Open spreadsheet Do these data indicate that the mean age of British men at the time of marriage exceeds the mean age in 2013? Test this hypothesis at a = 0.01. What is your conclusion? Use the obtained rounded values in your calculations. Sample mean: Sample standard deviation: t-value: p-value (Upper Tail): Because p-value O a = 0.01, we Ho. There is Check My Work years (to 2 decimals) years (to 4 decimals) (to 3 decimals) (to 3 decimals) evidence to conclude that the mean age at which British men get married exceeds what it was in 2013.

Condé Nast Traveler conducts an annual survey in which readers rate their favorite cruise ship. All ships are rated on a 100-point scale, with higher values indicating better service. A sample of ships that carry fewer than 500 passengers and a sample of ships that carry 500 or more passengers is provided in the Microsoft Excel Online file below (Condé Nast Traveler, February 2008). Round your all answers to two decimal places. Open spreadsheet a. What is the point estimate of the difference between the population mean rating for ships that carry fewer than 500 passengers and the population mean rating for ships that carry 500 or more passengers? b. At 95% confidence, what is the margin of error? c. What is a 95% confidence interval estimate of the difference between the population mean ratings for the two sizes of ships? to
