The following diastolic blood pressures were obtained from 20 females who were over 60 years of age. Find a 95% confidence interval for the median diastolic reading for the population of females over 60. (72, 74, 75, 77, 78, 79, 80, 81, 84, 85, 86, 88, 90, 90, 94, 96, 98, 100, 104, 106) Enter the lower limit Enter the upper limit Solution Mean = 86.85 S.D = 10.184 Z = 1.96 N = 20 CI = (Mean +/- Z*S.D)/sqrt(N) = 82.38 is the lower limit 91.31 is upper limit.
