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. 2.45, 0.51, 2.89, -0.8, 2.65, -0.87, -1.37, -2.76, - 1.27, - 1.45, -2.78, -1.28, -2.13, -2.46, 0.78, 1.19, 0.73, 2.81, 1.62 Send data to calculator Send data to Excel 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
