An airline's data indicate that 50% 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, seat selection, and payment, can be done in two pages rather than the current four. A random sample of 300 customers who begin the booking process are presented with the new system, and 117 of them do NOT complete the booking process. Based on this sample, do the data provide enough evidence to conclude that the new system has reduced the proportion of people who fail to complete the booking process?Conduct a hypothesis test at the 10% significance level. a. State the null and alternative hypotheses. b. Calculate the value of the test statistic. c. Draw the critical region and identify the critical value. d. Assess the evidence (e. g., does the test statistic fall into the critical region).e. State your conclusion in terms of the problem.
