According to the Bureau of Transportation Statistics, on-time performance by airlines is described as follows: Action Sof time On Time National Aviation System Delay 71 9 Aircraft arriving late Other (weather and other conditions) 12 When a study was conducted it was found that of the 208 randomly selected flights, 144 were on time, 15 were a National Aviation System Delay, 17 arriving late , 32 were due to weather. Perform a test to see if there is sufficient evidence at a = 0.05 to see if these differ from the governments statistics. The correct hypotheses are: O Ho: The sample is a good fit to the Bureau of Transportation Statistics. H: The sample is not a good fit to the Bureau of Transportation Statistics. (claim) O Ho: The sample is not a good fit to the Bureau of Transportation Statistics. H: The sample is a good fit to the Bureau of Transportation Statistics.(claim) A Ho: The sample and the Bureau of Transportation Statistics are independent. HA: : The sample and the Bureau of Transportation Statistics are dependent. (claim) O Ho: The sample and the Bureau of Transportation Statistics are dependent. H: The sample and the Bureau of Transportation Statistics are independent. (claim) The test value is (round to 3 decimal places) The p-value is (round to 3 decimal places) The correct decision is to reject Ho do not reject H, The final conclusion is There is enough evidence to reject the claim. There is not enough evidence to reject the claim. There is enough evidence to support the claim. There is not enough evidence to support the claim.
