A certain brokerage house wants to estimate the mean daily return on a certain stock. A random sample of 12 days yields the following return percentages. 0.37, 2.44, 0.54, -2.46, 1.9, -2.06, -2.79, 2.88, -2.75, 0.22, -1.22, -2.99 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: 0 Upper limit: 0 Х ?
