Sample Questions for Class Test preparation: Une Festival Cruise Lines and Fantastica Cruise Lines both have large fleets of cruise ships. A random sample of 25 cruise ships from each cruise line was selected and the following information was recorded on each ship: ShipName Name of ship Cruise Line: 1 = Fantastica, 2 - Festival Age Age of ship in 2015 (in years) Tonnage Carrying capacity of ship 1000s of tons) Passengers 2013 Number of passengers in 2013 Passengers2015 Number of passengers in 2015 Length Length of ship (meters) Cabins Number of cabins Crew Number of crew in 2015 Open the Cruise Ship.csv file which is provided with this test and which contains the information described above and carry out the appropriate analyses to answer the questions which follow. Choose from the most correct answer where appropriate, Question 1 Is the average number of cabins in cruise ships owned by Fantastica different to the average number of cabins in cruise ships owned by Festival Cruise Lines? 1. The most appropriate test to answer this research question is a: A Paired t-test B. Two-sample t-test t-test for the slope of the least squares regression line 2. Assuming any other test assumptions are reasonable, obtain histogram/s to check the normality assumption and select the most appropriate answer: A The assumption that the differences between each pair is normally distributed appears to be reasonable B. The assumption that the numbers of cabins in each cruise line is normally distributed appears to be reasonable c The assumption that the residuals are normally distributed appears to be reasonable 3. The test statistic for the test is (2dp) 4. The degrees of freedom is 5. The p value is (dp) 6. The most appropriate conclusion is: A The average number of cabins is significantly higher for Fantastica's cruise ships B. The average number of cabins is significantly higher for Festival's cruise ships The average number of cabins may be the same for Fantastica cruise ships and for Festival cruise ships
