According to the Bureau of Transportation Statistics, on-time performance by airlines is described as follows: Action % of time On Time National Aviation System Delay Aircraft arriving late Other (weather and other conditions) 70 7 15 When a study was conducted it was found that of the 235 randomly selected flights, 160 were on time, 16 were a National Aviation System Delay, 24 arriving late , 35 were due to weather. Perform a test to see if there is sufficient evidence at a = 0.01 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) 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. 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. There is not enough evidence to reject the claim. There is enough evidence to support the claim. O There is not enough evidence to support the claim.

Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
