Expedia is investigating if the month of travel impacts the online flight ticket purchases (i. e., number of tickets purchased online via Expedia webpage during that month). The statistical analysis team collects information on number of flights booked during each month over the past 10 years and run a statistical test to test whether the average number of flight tickets purchased are same across all months or if some months are different than others. Required:
a. What type of statistical test would you recommend? Why? Explain your response.
b. What is/are the factor(s)? What are the levels? What is the response? How many replicates are there?
