You are interested in finding a 95% 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. 23 6 13 25 11 23 21 6 12 26 a. To compute the confidence interval use a T or Z distribution? b. With 95% confidence the population mean number of visits per physical therapy patient is between _____ and _____ visits. 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.
