An airline’s data indicate that 50 percent of people who begin the online process of booking a flight never complete the process and pay for the flight. To reduce this percentage, the airline is considering changing its website so that the entire booking process, including flight and seat selection and payment, can be done on two simple pages rather than the current four pages. A random sample of 300 customers who begin the booking process are exposed to the new system, and 117 of them do not complete the process.Formulate the null and alterative hypotheses needed to attempt to provide evidence that the new system has reduced the non-completion percentage.Use the critical value approach to test the hypotheses by setting α equal to 0.10, 0.05, 0.01 and 0.001.Use the p-value approach to test the hypotheses by setting α equal to 0.10, 0.05, 0.01 and 0.001.

Question

An airline’s data indicate that 50 percent of people who begin the online process of booking a flight never complete the process and pay for the flight. To reduce this percentage, the airline is considering changing its website so that the entire booking process, including flight and seat selection and payment, can be done on two simple pages rather than the current four pages. A random sample of 300 customers who begin the booking process are exposed to the new system, and 117 of them do not complete the process.
1. Formulate the null and alterative hypotheses needed to attempt to provide evidence that the new system has reduced the non-completion percentage.
2. Use the critical value approach to test the hypotheses by setting α equal to 0.10, 0.05, 0.01 and 0.001.
3. Use the p-value approach to test the hypotheses by setting α equal to 0.10, 0.05, 0.01 and 0.001.
