Question

According to the Bureau of Transportation Statistics, on-time performance by airlines is described as follows:

Action	% of time
On Time	69
National Aviation System Delay	8
Aircraft arriving late	9
Other (weather and other conditions)	14

When a study was conducted it was found that of the 247 randomly selected flights, 178 were on time, 17 were a National Aviation System Delay, 25 arriving late , 27 were due to weather. Perform a test to see if there is sufficient evidence at αα = 0.10 to see if these differ from the governments statistics.

The correct hypotheses are:

H0:H0: The sample is a good fit to the Bureau of Transportation Statistics.

HA:HA: The sample is not a good fit to the Bureau of Transportation Statistics.(claim)
H0:H0: The sample is not a good fit to the Bureau of Transportation Statistics.

HA:HA: The sample is a good fit to the Bureau of Transportation Statistics.(claim)
H0:H0: The sample and the Bureau of Transportation Statistics are independent.

HA:HA: The sample and the Bureau of Transportation Statistics are dependent.(claim)
H0:H0: The sample and the Bureau of Transportation Statistics are dependent.

HA: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
