A random sample of 14 health maintenance organizations (HMOs) was selected. For each HMO, the co-payment (in dollars) for a doctor's office visit was recorded. The results are as follows. 59, 48, 31, 43, 29, 45, 48, 49, 45, 37, 55, 59, 52, 50 Send data to calculator Send data to Excel Under the assumption that co-payment amounts are normally distributed, find a 95% confidence interval for the mean co-payment amount in dollars. Give the lower limit and upper limit of the 95% confidence interval. Carry your intermediate computations to at least three decimal places. Round your answers to one decimal place. (If necessary, consult a list of formulas.) Lower limit: X Upper limit
