A special diet is intended to reduce systolic blood pressure among patients diagnosed with stage 2 hypertension. If the diet is effective, the target is to have the average systolic blood pressure of this group be below 150. After six months on the diet, an SRS of 28 patients had an average systolic blood pressure of = 143, with standard deviation s = 21. Is this sufficient evidence that the diet is effective in meeting the target? Assume that 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...

The following are the Systolic blood pressure (mm Hg) of 12 patients undergoing drug therapy for hypertension: 183, 152, 178, 157, 194, 163, 144, 114, 178, 152, 118, 158. Please use the sign test to test if there is evidence that the median of the blood pressures of the population from which we assume this sample to have been drawn is different from 135 mmHg (the norm for the group). level of significance .05

Question 5 [10 points] A doctor at a walk-in clinic is studying high blood pressure among patients of the ages twenty to forty. According to the American Heart Association, a person has high blood pressure if their Systolic and Diastolic readings are above 130 and 39 respectively. A random sample of 10 patients revealed the following blood pressures, where the readings (x,y) correspond to (Systolic Diastolic blood pressures (179,109) (180,120) (11970) (130,85) (159,90) (110,79) (180,120) (119,70) (110,79) (159,90) Assume that...

Question 9 > 51 The effectiveness of a blood-pressure drug is being investigated. An experimenter finds that, on average, the reduction in systolic blood pressure is 85.5 for a sample of size 796 and standard deviation 9.1. Estimate how much the drug will lower a typical patient's systolic blood pressure (using a 90% confidence level). Enter your answer as a tri-linear inequality accurate to one decimal place (because the sample statistics are reported accurate to one decimal place). Answer should...

Question 12 0 pts Suppose a hypertension trial is mounted and 18 participants are randomly assigned to one of the comparison treatments so that each treatment group has 6 participants. Each participant takes the assigned medication and their systolic blood pressure (SBP) is recorded after 6 months on the assigned treatment. The ANOVA table is as follows (You should be able to figure out values in the numbered cells): Source Between-Group 2376.8 Within-Group 846.2 Total Sum of Squares df Mean...

Question 1 marks In a study concerned with the effects of smoking on blood pressure, the smoking status (Yes - 1, No and systolic blood pressure (mmHg) were recorded for 500 randomly selected people. The purpose of the following analysis is to determine whether the systolic blood pressure of smokers is significantly different from that of non-smokens. The data are available on MyUni in the file BP.csv. (a) Explain briefly why the data should be treated as two independent samples...
