A certain brokerage house wants to estimate the mean daily return on a certain stock. A random sample of 10 days yields the following return percentages. -2.1, -1.77, 0.35 , 2.08, 1.98, 0.08, -2.89,-2.79, -2.48, 2.56 Send data to calculator Send data to Excel If we assume that the returns are normally distributed, find a 99% confidence interval for the mean daily return on this stock. Give the lower limit and upper limit of the 99% confidence interval. Carry your intermediàte computations to at least three decimal places. Round your answers to one decimal place.
