A medical researcher wishes to try three different techniques to lower cholesterol levels of patients with high cholesterol levels. 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 cholesterol level is recorded. Test the hypothesis that there is no difference among the means. Use a = 0.05. Apply p-value approach.

A medical researcher wishes to try three different techniques to lower cholesterol levels of patients with high cholesterol levels. 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 cholesterol level is recorded. Test the hypothesis that there is no difference among the means. Use α = 0.05. Apply p-value approach. Round p-value to nearest thousandth.

Transcribed Image Text:Steps for Hypothesis testing.
Step1)State null and Alternative Hypothesis.
Step2) Apply p-value and Classical(Traditional) Approach
Classical Approach: CV vs Test Statistic
p-value Approach: p-value vs Alpha (Level of Significance)
Step3)
State conclusion.
Claim is Alternative Hypothesis:
Reject Null Hypothesis: There is sufficient evidence to conclude that
Do not reject Null Hypothesis: There is insufficient evidence to conclude that
Claim is Null Hypothesis:
Reject Null Hypothesis: There is sufficient evidence to reject that
Do not reject Null Hypothesis: There is insufficient evidence to reject that
