Question
You are interested in finding a 90% confidence interval for the mean number of visits for physical
therapy patients. The data below show the number of visits for 15 randomly selected physical
therapy patients. Round answers to 3 decimal places where possible.
22 12 6 23
13 12 28 14 10
13 18

11 19 18
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 15 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.
