Can I get the solution for part (d) and (e)?

ANSWER ALL I. A research organization was hired by a vehicle rental agency, operating in the tourism sector of a Caribbean Island, to investigate the fuel efficiency of new imported mountain bikes. A stratified random sample was taken of new mountain bikes with permission from the different vehicle dealerships with the stratification factor being country of origin. The data collection focused on gasoline mileage (kilometres per litre). These were entered on a Minitab spreadsheet for analysis, Exhibit I below was subsequently generated. Exhibit 1 Country of 5% Tri N Mean Median St. Dev. S. E. Mean Origin Mean Malaysia 12.13 10.74 10.53 6.677 Europe 14.89 16.63 16.50 6.724 0.853 Japan 20.45 20.40 20.41 0.509 (a) Determine the values for * and "* [2 marks] Give both the point estimator and point estimate for the mean mileage of all new Malaysian bikes imported into this Caribbean Island. [2 marks] C) Give both the point estimator and point estimate for the varivice of the mileage of all new Japanese bikes imported into this Caribbean Island. [2 marks] (d) Hence, assuming normality, construct a 99% confidence interval for the mean mileage of all new Japanese bikes imported into this Caribbean Island 21. 76, 14.14 [3 marks] Give an interpretation of the confidence interval that you constructed above.
