The mean diastolic blood pressure for a random sample of
70
people was
90
millimeters of mercury. If the standard deviation of individual
blood pressure readings is known to be
10
millimeters of mercury, find a
95%
confidence interval for the true mean diastolic blood pressure
of all people. Then complete the table below.
Carry your intermediate computations to at least three decimal
places. Round your answers to one decimal place. (If necessary,
consult a list of formulas.)
