Let's assume that Delta Airlines reports the following information about seat preferences among U.S. travelers who took a Delta flight to/from at least one domestic airport during the past 3 months: 30% prefer an aisle seat 20% prefer a window seat 20% prefer an exit row seat 10% prefer a middle seat 10% prefer to sit in Delta Comfort Plus 10% prefer to sit in the main cabin

Let's further assume that you randomly surveyed 400 Delta passengers with similar flight experiences and asked them to specify their seat preferences. A copy of these data is contained in the Excel file titled "Week 13 Graded Assignment Data." For the reader's convenience these data are summarized in the table below.

Seat Preference f Aisle =125 Window =77 Exit Row =90 Middle -31 Delta Comfort Plus =42 Main Cabin = 35 A. Pre-Data Analysis 1. What is the research question and corresponding operational definitions? 2. What is the research methodology/design and why is this methodology appropriate? 3. Conduct an a priori power analysis to determine the minimum sample size needed. Is the given data set sufficient relative to this minimum sample size? In what way do you think the size of the given sample will impact the results?
