A major airline company is concerned that its proportion of late arrivals has substantially increased in the past month. Historical data shows that on the average 18% of the company airplanes have arrived late. In a random sample of 1,240 airplanes, 260 airplanes have arrived late. If we are conducting a hypothesis test of a single proportion to determine if the proportion of late arrivals has increased using the following hypothesesH0: p 0.18 and Ha: p > 0.18

Step 1 of 3: What is the value of the test statistic?Round your answer to four decimal places.

Step 2 of 3: calculate the p-value?Round your answer to four decimal places.

Step 3 of 3: We can conclude...

A.At the 5% level of significance, we should reject the nulll hypothesis and conclude the the proportion of late arrivals has increased.

B.At the 5% level of significance, we should reject the nulll hypothesis and conclude the the proportion of late arrivals has not changed.

C.At the 5% level of significance, we fail to reject the nulll hypothesis and conclude that no evidence exists to indicate that the the proportion of late arrivals is more than 18%.

D.At the 5% level of significance, we fail to reject the nulll hypothesis and conclude that no evidence exists to indicate that the the proportion of late arrivals is less than 18%.

E.None of the above
