An irate patient complained that the cost of a doctor’s visit
was too high.
She randomly surveyed 20 other patients and found that the mean
amount of money they
spent on each doctor’s visit was $44.80. The standard deviation of
the sample was $3.53.
Find a point estimate of the population mean. Find the 95%
confidence interval of the
population mean. Assume that the population is normally
distributed.
