A certain brokerage house wants to estimate the mean daily return on a certain stock. A random sample of 13 days yields the following return percentages. 1.57, -2.53, 1.13, 1.27, 0.53, -1.91, 2.6, 2.12, 1.36, 0.49, -0.67, -1.03, 0.62 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 5 ? Upper limit
