Based on a sample, the proportion of First-Class flight passengers arriving late (less than one hour before the scheduled departure time) at the check-in is estimated to be 0.30 (1). A similar study for Economy passengers yields an estimate of 0.36 (2). Both estimates are sample proportions based on 250 observations. 95% Confidence Interval: __________ < < ________ b.)The null hypothesis is that the population proportions are equal. The alternate hypothesis is that the population proportions are not equal. c. to perform a hypothesis test consistent with the problem as stated. Use a = 0.05.
