Recently, the number of airline companies that offer in-flight Wi-Fi service to passengers has increased. However, it is estimated that only 13% of the passengers who have Wi-Fi available to them are willing to pay for it. Suppose the largest provider of airline Wi-Fi service, would like to test this hypothesis by randomly sampling 160 passengers and asking them if they would be willing to pay $4.95 for 90 minutes of onboard Internet access. Suppose that 23 passengers indicated they would use this service. Using a = 0.05, complete parts a and b below. a. What conclusions can be drawn about the proportion of airline passengers willing to pay for onboard Wi-Fi service? Determine the null and alternative hypotheses. Choose the correct answer below. OA. Ho: p≤0.13 H₁: p > 0.13 C. Ho: p>0.13 H₁: p≤0.13 OB. Ho: p20.13 H₁: p<0.13 D. Ho: p=0.13 H₁: p *0.13

Determine the critical value(s) of the test statistic. Za (Use a umma to separate answers as needed. Round to two decimal places as needed.) Calculate the test statistic. (Round to two decimal places as needed.) Determine the proper conclusion. Choose the correct answer below. A. Do not reject Ho. There is insufficient evidence that the proportion of people with credit scores below 600 has increased XB. Reject Ho. There is insufficient evidence that the proportion of people with credit scores below 600 has increased. C. Reject Ho. There is sufficient evidence that the proportion of people with credit scores below 600 has increased. OD. Do not reject Ho. There is sufficient evidence that the proportion of people with credit scores below 600 has increased b. Determine the p-value for this test.. p-value= (Round to three decimal places as needed.) CC €
