A medical researcher wishes to see if he can lower the cholesterol levels through diet in 6 people by showing a film about the effects of high cholesterol levels. The data are shown. At -0.01, did the cholesterol level decrease on average? Use the P-value method and tables Patient 1 2 345 6 Before240 211 209 216 207219 After228 208196 194 205 214

A study was conducted at an American medical center and heart-attack incidents. A random sample of 30 heart-attack patients had their cholesterol levels measured two days after the attack. In addition, cholesterol levels were measured for a control group of 30 people who had not had a heart attack. The unitsf cholesterol measurement are mg/dL of blood. The two data sets are below regarding blood cholesterol levels DATA SET 1: HEART ATTACK GROUP (Assume that σ=46.63). 270 236 210 142...
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...
5. A medical researcher wishes to see whether the variance of the heart rates (in beats per minute) of smokers is different from the variance of heart rates of people who do not smoke. Below is the data from two samples. Using a = 0.05, is there enough evidence to support the claim? (10 points) Smokers Non-Smokers n1 = 26 S12 = 32 n2= 18 s22 = 10

Provide an appropriate response. 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. Find the critical value Foto test the claim that there is no difference...
Maintaining a healthy weight is important for women’s health. Some physicians recommend being back to your pre-pregnancy weight six months after giving birth. Public health officials are interested in whether this is a realistic goal. Do the women in North Carolina weigh more than their pre-pregnancy weight six months postpartum? In other words, is the six months post-pregnancy weight greater than their pre-pregnancy weight? Use a paired samples t-test to compare pst6wght (variable 1) and prewght (variable 2). This uses...
