a 3. The high cost of health care is a matter of major concern for a large number of families. A random sample of 25 families selected from an area showed that they spend an average of $143 per month on health care with a standard deviation of $28. Make 99% confidence interval for the mean health care expenditure per month incurred by all families in this area. Assume a normal distribution (Hint t distribution - Chap 8) a. Construct a 99% confidence interval.
