A random sample of 15 health maintenance organizations (HMOS) was selected. For each HMO, the co-payment (in dollars) for a doctor's office visit wasrecorded. The results are as follows.7, 5, 5, 9, 6, 7, 9, 9, 10, 11, 7, 11, 10, 5, 6Send data to calculatorSend data to ExcelUnder the assumption that co-payment amounts are normally distributed, find a 90% confidence interval for the mean co-payment amount in dollars. Then findthe lower limit and upper limit of the 90% 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:||Upper limit: I

The Nenana Ice Classic is an annual contest to guess the exact time in the spring thaw when a tripod erected on the frozen. Tanana River near Nenana, Alaska, will fall through the ice. The contest has been run since 1917. The 2017 jackpot was $267,444. The table gives simplified data that record only the date on which the tripod fell each year. The earliest date so far is April 20. To make the data casier to use, the table gives the date each year in days starting with April 20. That is, April 20 is 1, April 21 is 2, and so on.
