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. 0.46,-1.46, 1.91, 2.83, 1.45,-1.02, 0.32, 2.21, -0.42,-0.85, -2.18,-2.55 Send data to calculator Send data to Excel If we assume that the returns are normally distributed, find a 95% confidence interval for the mean daily return on this stock. Then find 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:I Upper limit:
