. Calculate the proportion of sampled airline flights that landed within 15 minutes of scheduled arrival.

_____________ ​(Round to three decimal places as​ needed.)

b. Calculate the probability that a sampled proportion of​ on-time flights would be within plus or minus0.05 of a population proportion equal to 0.737.

____________ ​(Round to four decimal places as​ needed.)

c. If the​ airlines’ goal was to attain the same proportion of​ on-time arrivals as the previous​ year, do the preliminary results indicate that they have met this​ goal? Support your assertions.

A. The sample proportion is outside the interval found in part b. There is a large chance that a sample proportion would be outside this interval given the population proportion is still 0.737.

B. The sample proportion is contained in the interval found in part b. There is a large chance that a sample proportion would be contained in this interval given the population proportion is still 0.737.

C. The sample proportion is contained in the interval found in part b. There is a small chance that a sample proportion would be contained in this interval given the population proportion is still 0.737.

D. The sample proportion is outside the interval found in part b. There is a small chance that a sample proportion would be outside this interval given the population proportion is still 0.737.
