You are interested in finding a 95% confidence interval
for the mean number of visits for physical therapy

a. To compute the confidence interval use a ( ?
distribution.
b. With 95% confidence the population mean number of
visits per physical therapy patient is between
and
visits.
c. If many groups of 11 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
percent will not contain the true population
about
mean number of visits per patient.
