Question
Expedia would like to test the hypothesis that the proportion of United Airline flights that arrive on-time is less than 0.80. A random sample of 110 United Airline flights found that 82 arrived on-time. Expedia would like to set a = 0.02. Which one of the following statements is true? a. Because the p-value is less than a, we reject the null hypothesis and conclude that the proportion of United Airline flights that arrive on-time is less than 0.80. O b. Because the p-value is greater than a, we reject the null hypothesis and cannot conclude that the proportion of United Airline flights that arrive on-time is less than 0.80. C. Because the p-value is less than a, we fail to reject the null hypothesis and cannot conclude that the proportion of United Airline flights that arrive on-time is less than 0.80. d. Because the p-value is greater than a, we fail to reject the null hypothesis and cannot conclude that the proportion of United Airline flights that arrive on-time is less than 0.80.
