A random sample of 18 health maintenance organizations (HMO) were selected. For each HMO, the copayment in dollars for a doctors office visit was recorded. The results are as follows. 53,38,48,42,28,25,38,27,29,53,29,54,25, 36,41,53,56,56 under the assumption that copayment amounts are normally distributed, find a 90% confidence interval for the mean copayment a mountain dollars. Give the lower limit and upper limit of a 90% confidence interval. Carrier intermediate computation so at least three decimal places. Round your answer to one decimal place.
