. Hypothesis Testing [20pts 10, 10] A regional airline company is planning on purchasing 50 new aircras to expand their network and retire older, less efcient aircrafts. The two models under consideration are the Boeing 737-800 and Airbus A220300. From a set of tests performed on the max range of the aircraft, the following data were obtained for 12 samples for the Boeing 737-800 and 11 samples for the Airbus A220300- Since Boeing is the more well-established and the popular aircraft manufacturer, the airline company will not adopt the Airbus A220-300 unless its mean max range in km exceeds that of the Boeing 73 7-800 by at least 300 km. Assume that the max ranges of the aircras are normally distributed, and the two samples are independent. Max Range in KM Data: A220 = c(6020.524, 6127.773, 6384.523, 6113.833, 6275.146, 6219.587, 5957.506, 6306.774, 6429.327, 6150-374, 6386.445) B737 = c(6122-516, 5826.997, 5824.255, 5996-815, 5882-094, 6098.454, 5610.449, 5625.267, 5767.400, 5666-078, 5546-324, 5660.887) A. Now as a data analyst in the airline company, you want to help your company make the purchasing decision by running a hypothesis testing. Please use the equal variance assumption and H1: pawn, gaming 2: 300- What's your conclusion here with a = 0.05. B. Is the equal variance assumption reasonable? Run a hypothesis test on the ratio of two variances to verify it with o: = 0.1- Write down your hypotheses precisely and use the corresponding CUCB to make your conclusion. You should state your reasoning clearly
