A researcher wishes to investigate the idea that eating sea salt raises blood pressure less than eating normal table salt. He randomly selects two groups, each with 13 people. He arranges that Group 1 will be on a high sea salt diet for 2 weeks, while Group 2 will be on a high table salt diet. He measures their blood pressure after the two weeks. The mean systolic blood pressure for Group 1, x¯1x¯1, is found to be 126 with...

To determine whether high blood pressure affected whether a person had a stroke, a sample of 121 people who had had strokes are examined. In the sample, 40% had high blood pressure. If we were to test the hypothesis that at least 33% of the people who have had strokes have had high blood pressure (using the 10% level of signficance) what is the critical value? (please round your answer to 2 decimal places)

The blood pressure of a person changes throughout the day. Suppose the systolic blood pressure of a person is measured 24 times over several days and the standard deviation of these measurements for the person is known to be σ=9 σ = 9 mmHg. Let μ μ be the true average blood pressure for that person and let x¯=96 x ¯ = 96 be the average of the 24 measurements. (a) Find a two-sided 91% confidence interval for μ.μ. One...

The blood pressure of a person changes throughout the day. Suppose the systolic blood pressure of a person is measured 16 times over several days and the standard deviation of these measurements for the person is known to be σ=7.9 mmHg. Let μ be the true average blood pressure for that person and let x¯=127 be the average of the 16 measurements. (a) Find a two-sided 94% confidence interval for μ. One can be 94% confident that the true average...

A nutritionist is interested in the effect of eating a vegetarian diet on blood pressure. Specifically, she is interested in determining if vegetarians have lower systolic blood pressure readings than omnivores. A sample of eight vegetarians and eight omnivores were randomly selected from a normal population to participate in the study. The systolic blood pressure levels of each group were measured and the results are recorded in the following table. use an alpha level of α = .05. Systolic Blood...

Frank- has high blood pressure. Blood pressure is affected by heart rate (higher heart rate increases pressure), vasomotor tone (more vasoconstriction increases pressure), and blood volume (we will not consider this factor in this question) Of the pharmaceutical (medication/drug) types listed below, which is/are most likely to help Frank reduce his blood pressure? For each, EXPLAIN HOW the drug would either help or harm Frank. A drug that blocks beta-1 receptors A drug that activates beta-2 receptors A drug that...

Dentists make many people nervous. To see whether such nervousness elevates blood pressure, the blood pressure and pulse rates of 60 subjects were measured in a dental setting and in a medical setting. For each subject, the difference (dental-setting blood pressure minus medical-setting blood pressure) was calculated. The analogous differences were also calculated for pulse rates. Summary data are given below. Mean Difference Standard Deviation of Differences Systolic Blood Pressure   4.43 8.77 Pulse (beats/min) −1.30 8.84 (a) Do the data...
