This problem is to be solved by hand.

The weight and systolic blood pressure of 12 randomly selected males in the age group 25-30 are shown in the table below.

Subject 1 2 3 4 5 6 7 8 9 10 11 12

Weight (lbs), x 165 167 180 165 212 175 190 212 200 149 158 169

Systolic BP, y 130 133 150 128 151 146 150 140 148 125 133 135

(e) Test for significance of regression coefficient using the two-sided t-test and a = 0.05.

(f) Construct an analysis of variance table and use it to perform the hypothesis test of part (e). Restate the null and alternative hypotheses and interpret your results.

(g) Perform a residual analysis on the data.

(h) Summarize your analysis of parts (a)-(g) in paragraph form to determine the appropriateness of the model.

A pharmaceutical company claims that its new drug reduces systolic blood pressure. The systolic blood pressure (in millimeters of mercury) for nine patients before taking the new drug and 2 hours after taking the drug are shown in the table below. Is there enough evidence to support the company's claim? Let d = (blood pressure before taking new drug) − (blood pressure after taking new drug). Use a significance level of α = 0.05 for the test. Assume that the...

A pharmaceutical company claims that its new drug reduces systolic blood pressure. The systolic blood pressure (in millimeters of mercury) for nine patients before taking the new drug and 2 hours after taking the drug are shown in the table below. Using this data, find the 99% confidence interval for the true difference in blood pressure for each patient after taking the new drug. Assume that the blood pressures are normally distributed for the population of patients both before and...
