The ages (in years) of nine men and their systolic blood pressures (in millimetres of mercury) are given below.

Age	16	25	39	49	22	57	22	63	75
Systolic blood pressure	109	122	143	199	118	175	118	185	199

Name the dependent and independent variables
Calculate the correlation coefficient and interpret your results.
Calculate the rank difference correlation coefficient
Develop the regression equation for the data set.
Predict the blood pressure of a 50-year-old and a 70-year-old.
Discuss the usefulness of this information to Senior Citizens.
Examine the assumptions for regression analysis?

Expert Solution

a. dependent is Systolic blood pressure and independent variable is Age.

b.

c.

d.

e.

Fro X=50, Y = 83.9873 + 1.6634*50 = 167.1573

Fro X=70, Y = 83.9873 + 1.6634*70 = 200.4253

How are systolic and diastolic blood pressures measured with a sphygmomanometer?

The systolic blood pressures of the patients at a hospital are normally distributed with a mean...

The systolic blood pressures of the patients at a hospital are normally distributed with a mean of 136 mm Hg and a standard deviation of 13.8 mm Hg. Find the two blood pressures having these properties: the mean is midway between them and 90% of all blood pressures are between them. Need step by step on how to get answer

The distribution of systolic blood pressures in a group of females with diabetes is approximately normal...

The distribution of systolic blood pressures in a group of females with diabetes is approximately normal with unknown mean. Fortunately, the standard deviation is known: σ= 11.8 mm/Hg. In a sample of 10 women from this group the mean systolic blood pressure was x̅= 130 mmHg. Calculate a two-sided 95% confidence interval for the true mean systolic blood pressure, μ, for the group of diabetic women Repeat (a) but construct a 90% confidence interval instead. How does the two confidence...

In a clinic, the systolic blood pressures in mmHg of a random sample of 10 patients with a certain metabolic disorder were collected. Assume blood pressure is normally-distributed in the population. The mean of this sample was 103.2 mmHg with a (sample) standard deviation of 15.0 mmHg. Test the hypothesis that the mean blood pressure of this sample of patients differs from the known population mean sysolic blood pressure of 121.2 mmHg. Show your working including null hypothesis, alternative hypothesis,...

The distribution of diastolic blood pressures for the population of female diabetics between the ages of 30 and 34 has an unknown mean and standard deviation. A sample of 10 diabetic women is selected; their mean diastolic blood pressure is 84 mm Hg. We want to determine whether the diastolic blood pressure of female diabetics are different from the general population of females in this age group, where the mean  = 74.4 mmHg and standard deviation  = 9.1...
