Problem 2:
For a recent year, the mean fare to fly from Charlotte, North Carolina to Chicago Illinois, on a discount ticket was $290. A random sample of 12 round trip discount fares on this route last month shows:
286 |
290 |
285 |
291 |
287 |
275 |
262 |
289 |
274 |
276 |
297 |
262 |
At the 0.01 significance level, can we conclude that the mean fare has decreased? What is the p value?
