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 10 randomly selected physical therapy patients. Round answers to 3 decimal places where possible. 13 10 23 21 19 11 13 7 distribution. a. To compute the confidence interval use a b. With 98% confidence the population mean number of visits per physical therapy |x and |x visits patient is between c. If many groups of 10 randomly selected physical therapy patients are studied, then a different confidence interval would be produced from each group. About percent of these confidence intervals will contain the true population mean number of visits per patient and about |* percent will not contain the true population mean number of visits per patient.
