A certain brokerage house wants to estimate the mean daily return on a certain stock. A random sample of 14 days yields the following return percentages. 1.35, -1.12, -0.6, 2.38, -0.17, 2.59, -1.72, -2.28, 2.23, -1.54, 1.62, 2.37, 1.83, -1.01 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 5 ? Upper limit
