The following sample data represent the number of late and on time flights for the Delta, United and US Airways. Excel File: data12-19.xlsx Flight Late US Airways 56 On Time 344 a. Formulate the hypotheses for a test that will determine whether the population proportion of late flights is the same for all three airlines. Ho All population proportions are equal H₂ Not all population proportions are equal v b. Conduct the hypothesis test with a 0.05 level of significance. What is the p-value? Use Table 3 of Appendix B. The p-value is greater than 0.10 What is your conclusion? Airline United 51 249 Delta 39 261 (to 2 decimals) (to 2 decimals) Unable to reject the null hypothesis that the population proportions are same c. Compute the sample proportion of late flights for each airline. P₁ = P₂ = P3 = (to 2 decimals) What is the overall proportion of late flights for the three airlines? Round your answer to three decimal places. The overall proportion of late flights for the three airlines is
