Assignment B ( MLS)
a)Use the random number generator features in MyLab Statistics to generate 10 Diastolic blood pressures between 70 mm hg and 100 mm Hg. you may Excel to generate the numbers or make up your own number between 70 and 100. Find the mean, variance, standard deviation , and the coefficient of variations for two patients (Janet & James) for 10 straight days.
Dr. Courtney measured and recorded James and Janet’s diastolic blood pressures for 10 straight days for a particular study. Here are the results for each patient for that 10-day period. Yours will be different than the following sets of data:
(Janet’s DBP) James’s DBP
81 90
84 81
85 98
85 86
80 70
78 80
81 100
83 90
77 78
78 83
You will use a random number generator in MYLab Statistics to generate 10 Diastolic blood pressure numbers between 70, and 100 for each patient or you can simply make up your numbers.
a)Find the mean, variance, standard deviation, and the coefficient of variation (C.V)
b)Conduct an analysis within one standard deviation and 2 standard deviations of the mean
c) State Which DBP was more consistent during that 10- day period?
