The following data were randomly drawn from an approximately normal population. 26, 28, 31, 38, 44 Send data to calculator Send data to Excel Based on these data, find a 95% confidence interval for the population standard deviation. Then give its lower limit and upper limit. Carry your intermediate computations to at least three decimal places. Round your answers to at least two decimal places. (If necessary, consult a list of formulas.) Lower limit: X Upper limit
