A certain brokerage house wants to estimate the mean daily return on a certain stock. A random sample of 17 days yields the following return percentages. 1.73, -0.31, -1.26, 0.55, 1.16, -1.06, -2.09, -2.55,-1.56, -1.74, 1.51, 0.35, 2.95, 0.19, 0.37, -0.32, -1.73. Send 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
