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. -1.59, 2.19, -0.65, -2.19, 1.89, 296, -0.61, -2.22, -1.52, 0.61, 0.33, -1.53, 1.06 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. Give the lower limit and uppe limit of the 90% confidence interval.
