A certain brokerage house wants to estimate the mean daily return on a certain stock. A random sample of 16 days yields the following return percentages. - 0.69, -2.78, -2.79, 0.95, 0.21, -2.41, 2.87, 1.6, 2.16, -2.29, 0.09, -2.09, 2.6, 2.84, -2.89, -0.71 Send data to calculator If we assume that the returns are normally distributed, find a 90% confidence interval for the mean daily return on this stock. Give the 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: X Upper limit
