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 12 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¯1, is found to be 133 with...

A medical researcher wishes to try three different techniques to lower blood pressure of patients with high blood pressure. The subjects are randomly selected and assigned to one of three groups. Group 1 is given medication, Group 2 is given an exercise program, and Group 3 is assigned a diet program. At the end of six weeks, each subject's blood pressure is recorded. Test the claim that there is no difference among the means. Use α = 0.05. Resource: The...

.A special diet is intended to reduce cholesterol in people with high blood pressure. If the diet is effective, the target is to have the average cholesterol level of this group be below 150. After six months on the diet, a sample of 28 patients with high blood pressure had an average cholesterol level of x ̄ = 144 and a standard deviation of s = 21. Assume the distribution of the cholesterol for patients in this group is approximately...

3. Test the indicated claim about the means of two populations. Assume that the two samples are independent simple random samples selected from normally distributed populations. Do not assume that the population standard deviations are equal. Use the P-value method. A researcher wishes to determine whether people with high blood pressure can reduce their blood pressure, measured in mm Hg, by following a particular diet. Use a significance level of 0.01 to test the claim that the treatment group is...
