The airline industry defines "no-shows" as passengers who have purchased a ticket but fail to arrive at the gate on time for departure.United Airlines operates many flights from Philadelphia to Dallas.The table below represents the observed number of no-shows that occurred on a random sample of 120 flights between Philadelphia and Dallas this year,and experienced the no-show proportions last year. United Airlines would like to know if the proportions of no-shows has changed between last year and this year on flights between these two cities using α = 0.05.The conclusion for this hypothesis would be that because the test statistic is __________________________________________________________________________.
A) the test statistic is greater than the critical value;we can reject the null hypothesis and conclude that the proportions for no-shows has changed from last year to this year
B) the test statistic is less than the critical value;we can reject the null hypothesis and conclude that the proportions for no-shows has changed from last year to this year
C) the test statistic is greater than the critical value;we cannot reject the null hypothesis and conclude that the proportions for no-shows has changed from last year to this year
D) the test statistic is less than the critical value;we cannot reject the null hypothesis and conclude that the proportions for no-shows has changed from last year to this year
