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
(a) Plot the points on a scatter diagram. Does there appear to be a linear trend? Estimate the leastsquares regression line.
(b) Estimate the average systolic BP for a male that weighs 195.
(c) Construct a 95% confidence interval for b1. Interpret the interval.
(d) Construct a 95% confidence interval and a 95% prediction interval for the average systolic BP if x = 195 lbs. Explain the difference between these two intervals.
(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 resting systolic blood pressure (BP) of 120 mm Hg is stated to be the population mean for women. This was based on research conducted by several researchers on women from the healthy general public. Consider 20 first-year resident female doctors drawn at random. The resting systolic BP measured using an electronic sphygmomanometer are listed below. Is the sample significantly different from the population? State the null and alternative hypotheses Set the criteria for a decision: two-tailed test with a...
A blood pressure measurement consists of two numbers: the systolic pressure
1.A blood pressure measurement consists of two numbers: the systolic pressure, which is the maximum pressure taken when the heart is contracting, and the diastolic pressure, which is the minimum pressure taken at the beginning of the heartbeat. Blood pressures were measured, in millimeters of mercury, for a sample of 6 adults. The following table presents the results.SystolicDiastolic1348710869115831056611377157103Part 1 of 2 Compute the least-squares regression line for predicting diastolic pressure (v) from systolic pressure (x).

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 22 hours after taking the drug are shown in the table below. Using this data, find the 99%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...
