Extracted text: You are interested in finding a 98% confidence interval for the mean number of visits for physical therapy patients. The data below show the number of visits for 11 randomly selected physical therapy patients. Round answers to 3 decimal places where possible. 22 7 23 10 23 22 26 19 20 15 17 a. To compute the confidence interval use a t v distribution. b. With 98% confidence the population mean number of visits per physical therapy patient is between 8.83 and visits. c. If many groups of 11 randomly selected physical therapy patients are studied, then a different confidence interval would be produced from each group. About 98 percent of these confidence intervals will contain the true population mean number of visits per patient and about 2 percent will not contain the true population mean number of visits per patient.
