A certain brokerage house wants to estimate the mean daily return on a certain stock. A random sample of 19 days yields the following return percentages. 2.62, -2.66, 2.45, 0.47, 1.29, 2.06, -0.5, -2.85, -0.46, -0.01, 1.59, -0.13, -1.65, 1.92, 1.24, -1.03, -2.86, -0.02, 2.22 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 5 ? Upper limit: V
