You are interested in comparing the average, systolic blood
pressure of women athletes during intense exercise to the healthy,
systolic blood pressure of the general population when at rest
(i.e. not during exercise) (µ = 120).
Because exercise increases systolic blood pressure, you predict
that the average, systolic blood pressure for women athletes during
exercise will be significantly greater than the systolic, resting
blood pressure (µ = 120). Your alpha level is 0.05. (50
points)
Note: Your test value in...

Suppose you measured systolic blood pressure (unit: mmHg) of 20
individuals aged 40 to 60 living in LA, and obtained the following:
103, 115, 120, 123, 123, 128, 129, 130, 130, 132, 133, 137, 140,
140, 142, 148, 161, 165, 172, 195
1. Construct a frequency distribution with density using the
intervals corresponding to the American Heart Association’s blood
pressure categories for systolic blood pressure: normal: [100,120),
elevated: [120,130), hypertension stage 1: [130,140), hypertension
stage 2: [140,180), and hypertensive crisis:...

A medical researcher is investigating the effect of drinking
coffee on systolic blood pressure. The researcher assumes the
average systolic blood pressure is 120 mmHg. For a random sample of
200 patients, the researcher takes two measurements of systolic
blood pressure. The first systolic blood pressure measurement is
taken during a week when the patients drink no coffee, and the
second systolic blood pressure measurement is taken during a week
when the patients drink at least two cups of coffee....

A question of medical interest is whether jogging leads to a
reduction in systolic blood pressure. To learn about this question,
eight nonjogging volunteers have agreed to begin a 1-month jogging
program. At the end of the month their blood pressures were
determined and compared with earlier values, with the following
data resulting:
