Question 10 5.5 pts Best ontime airlines: Hawaiian Airlines topped the list of the most punctual U.S. airlines for full-year 2014, according to data released by the Bureau of Transportation Statistics. The on-time arrival performance was 91.9% Another aviation data service believes that this percentage now is even higher. The team of researchers chose 130 randomly selected flights and find that 120 of the flights arrived on time. Can a hypothesis test be used to determine whether the proportion of Hawaiian Airlines flights that arrive on-time is higher than 91.9 %2 Yes, because the sample is random. Thus, it is representative of the population of flights for the airlines Yes, because the sample is random and (130)(0.923) and (13010.077) are both at least 10. This means the normal model is a good fit for the sampling distribution. Yes, because the sample is random and (130 (0.919) and (13010.081) are both at least 10. This means the normal model is a good fit for the sampling distribution. Question 11 5.5 pts Delta Flights: According to the Bureau of Transportation Statistics. 77.4% of Delta Airline's flights arrived on time in 2010. The company is trying to improve on-time arrivals. They test the hypotheses Ho:p= 0.774 versus H:p> 0.774 They calculate a P-value of 0.03. Using a significance level of 0.05. which of the following is the hest explanation
