a. To compute the confidence interval use a ____distribution.
b. With 90% confidence the population mean number of visits per physical therapy patient is between ____ and _____ 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 ______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.
