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 $ 299 $ 290 $ 310 $ 250 $ 270 $ 330 $ 291 2$ 280 $ 265 $ 275 $ 281 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. а. b. Calculate the necessary statistics to perform that test. Using the 6-step hypothesis testing procedure, perform the test that you described above. Use a level с. 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?

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?
