For both airlines, (recall you already collected data on one airline in Module 1 and an additional airline as part of this assignment), construct 95 percent confidence intervals (alpha would equal what in this case?) for monthly load factors, monthly revenue passenger miles, and monthly available seat miles (Domestic flights only). There is a function in Excel that will calculate the confidence interval that needs to be added and subtracted from the mean to determine the 95 percent confidence interval. Develop the appropriate null and alternate hypotheses and test if the monthly load factors, monthly revenue passenger miles, and monthly available seat miles are equal for the two airlines (use alpha of 0.05). In addition, using the results from module 1 where you calculated the summary statistics for the items listed, test if the mean for each airline is equal to the mean for the industry for monthly load factors, monthly revenue passenger miles, and monthly available seat miles. After completing the above items, prepare a brief (one to two page) write-up of the analysis completed above. Items to include in your write-up include how a given airline is performing relative to industry and whether the results are consistent with expectations. For example, would you expect a single airline's available seat miles to be equal to the entire industry's? Your write-up should also include a brief discussion identifying where the data was obtained from. Cite sources and format your document in accordance with the current edition of the APA Manual. Be sure to include summary tables of summary statistics and a table summarizing the test results. Refer to the readings from Module 1 and the APA manual for formatting issues. Turn in two files for this assignment. One should include the write-up and the other the data and analysis.
