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 13 randomly selected physical therapy patients. lawn-- a. To compute the confidence interval use a ? c distribution. b. With 98% confidence the population mean number of visits per physical therapy patient is between C] and C] visits. c. If many groups of 13 randomly selected physical therapy patients are studied, then a different confidence interval would be produced from each group. About I: percent of these confidence intervals will contain the true population mean number of visits per patient and about [3 percent will not contain the true population mean number of visits per patient
