The mean diastolic blood pressure for a random sample of 70people was 90 millimeters of mercury. If the standard deviation ofindividual blood pressure readings is known to be 11 millimeters ofmercury, find a 90% confidence interval for the true mean diastolicblood pressure of all people. Then complete the table below. Carryyour intermediate computations to at least three decimal places.Round your answers to one decimal place. What is the lower limit ofthe 90% confidence interval? What is the upper limit of the 90%confidence interval?
