A certain brokerage house wants to estimate the mean daily return on a certain stock. A random sample of 17 days yields the following return percentages. -0.18, 2.94, 0.13, -0.75, 1.11, -2.88, 0.79, - 1.61, -0.36, -1.69, -1.27, 2.42, - 1.28, 0.5, 1.49, -0.93, 1.61 Send data to calculator Send data to Excel If we assume that the returns are normally distributed, find a 99% confidence interval for the mean daily return on this stock. Give the lower limit and upper limit of the 99% 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
