A certain brokerage house wants to estimate the mean daily return on a certain stock. A random sample of 20 days yields the following return percentages. -2.9, 1.82, - 1.79, - 2.59, 2.03, -2.02, 2.45, -0.81, -1.03, 0.15, 1.45, -2.64, 0.14, 0.26, 1.2, 1.6, 0.17, 1.19, 2.88, 2.62 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. Then find 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 P Upper limit
