According to the Bureau of Transportation Statistics, on-time performance by airlines is described as follows: Action % of time On Time 71 National Aviation System Delay 9. Aircraft arriving late 10 Other (weather and other conditions) 10 When a study was conducted it was found that of the 211 randomly selected flights, 150 were on time, 19 were a National Aviation System Delay, 21 arriving late , 21 were due to weather. Perform a test to see if there is sufficient evidence at a = 0.10 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. HA: 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. HA: The sample is a good fit to the Bureau of Transportation Statistics.(claim) O Ho: The sample and the Bureau of Transportation Statistics are independent. HA: The sample and the Bureau of Transportation Statistics are dependent. (claim)

When a study was conducted it was found that of the 211 randomly selected flights, 150 were on time, 19
were a National Aviation System Delay, 21 arriving late , 21 were due to weather. Perform a test to see if
there is sufficient evidence at a = 0.10 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.
HA: 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.
HA: The sample is a good fit to the Bureau of Transportation Statistics. (claim)
O Ho: The sample and the Bureau of Transportation Statistics are independent.
HA: The sample and the Bureau of Transportation Statistics are dependent. (claim)
Transcribed Image Text:O Ho: The sample and the Bureau of Transportation Statistics are dependent.
HA: 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
O reject Ho
O do not reject Ho
The final conclusion is
O There is enough evidence to reject the claim.
O There is not enough evidence to reject the claim.
O There is enough evidence to support the claim.
O There is not enough evidence to support the claim.
