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. -0.55, -2, -2.25, 0.24, 2.35, 1.96, 2.45, - 1.71, -2.93, 0.17, 1.06, - 1.55, 1.49, 0.5, 1.09, -1.8, -1.42, -2.86, 1.13 Send data to calculator If we assume that the returns are normally distributed, find a 95% confidence interval for the mean daily return on this stock. Give the lower limit and upper limit of the 95% 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
