According to a 2017 survey by a reputable organization, patients had to wait an average of 24 days to schedule a new appointment with a doctor. A random sample of 40 patients in 2018 was selected and the number of days they had to wait to schedule an appointment was recorded, with the accompanying results. Complete parts a and b. a. Perform a hypothesis test usingα=0.01 to determine if the average number of days appointments are booked in advance has changed since 2017. 1. Determine the null and alternative hypotheses. 2. Determine the appropriate critical value. 3. Select the correct choice below and fill in the answer box within your choice. (Round to three decimal places as needed.) A −tα= B.tα/2= C.tα= 4. Calculate the test statistic 5. P Value 6. State the conclusion
