Textbook example 5. For 2019, the mean fare to fly from Los Angeles to Miami was $275 on Aero Lindvallia. In September 2020, thirteen flights were randomly surveyed resulting in the following ticket price data being recorded:| $321 | $286 | $290 | $330 | $310 | $250 | $270 ||------|------|------|------|------|------|------|| $280 | $299 | $265 | $291 | $275 | $281 | |a. What test would you use to determine if the ticket prices had gone up or down? Is it a one-tailed or two-tailed test? Explain.b. Calculate the necessary statistics to perform that test.c. Using the 6-step hypothesis testing procedure, perform the test that you described above. Use a level of significance of 0.01. Comment on each step of the 6-step hypothesis testing procedure; especially explain why a t-distribution must be used.d. Compute the p-value. Would the results of the hypothesis test change if the level of significance was 0.05?
