Question
Is there sufficient evidence to reject the null hypothesis? (Use a 0.10 level of significance.)
OA. Reject the null hypothesis. There is sufficient evidence at the 0.10 level of significance that the population mean wait time is less than 25 minutes.
OB. Reject the null hypothesis. There is sufficient evidence at the 0.10 level of significance that the population mean wait time is greater than 25 minutes.
OC. Do not reject the null hypothesis. There is insufficient evidence at the 0.10 level of significance that the population mean wait time is less than 25 minutes
O D. Do not reject the null hypothesis. There is insufficient evidence at the 0.10 level of significance that the population mean wait time is greater than 25 minutes.
b. Interpret the meaning of the p-value in this problem.
Choose the correct answer below
OA. The p-value is the probability that the actual mean wait time is 23.22 minutes or less
OB. The p-value is the probability that the actual mean wait time is 25 minutes given the sample mean wait time is 23 22 minutes
OC. The p-value is the probability that the actual mean wait time is more than 23.22 minutes.
OD. The p-value is the probability of getting a sample mean wait time of 23.22 minutes or less if the actual mean wait time is 25 minutes.
