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 proportion 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) Reject the null hypothesis, we cannot conclude that the proportions for no-shows has changed from last year to this year
B) Reject the null hypothesis, we can conclude that the proportions for no-shows has changed from last year to this year
C) Do not reject the null hypothesis, we cannot conclude that the proportions for no-shows has changed from last year to this year
D) Do not reject the null hypothesis, we can conclude that the proportions for no-shows has changed from last year to this year
