Extracted text: No-shows 0 Frequency 10 12 3 14 15 14 18 26 32 20 United Airlines would like to know if the probability distribution of no-shows has changed between last year and this year on flights between these two cities using a = 0.05. The conclusion for this hypothesis test would be that because the test statistic is more than the critical value, we can reject the null hypothesis and conclude 1) that the probability distribution for no-shows has changed from last year to this year for flights between these two cities. less than the critical value, we can reject the null hypothesis and conclude O 2) that the probability distribution for no-shows has changed from last year to this year for flights between these two cities. more than the critical value, we cannot reject the null hypothesis and 3) conclude that the probability distribution for no-shows has changed from last year to this year for flights between these two cities. less than the critical value, we cannot reject the null hypothesis and cannot 4) conclude that the probability distribution for no-shows has changed from last year to this year for flights between these two cities.

United Airlines operates many flights from Philadelphia to Dallas and experienced the following no-show probability distribution last year.
