Identify the correct written form of the null hypothesis A. The mean cholesterol ratio between baseline and week 6 are equal B. The mean cholesterol ratio between the three test weeks are NOT equal C. The mean cholesterol ratio between baseline and week 6 are NOT equal D. The mean cholesterol ratio between the three test weeks are equal
According to the CDC, cholesterol levels can be reduced by following a healthy diet, getting regular exercise, and reducing the amount of alcohol consumed on a weekly basis. One method of monitoring overall cholesterol levels is to calculate your cholesterol ratio (LDL/HDL), in general a cholesterol ratio between 3.5 and 5.0 is considered to be healthy for most adults. Suppose you are a clinical researcher testing the effects of these lifestyle changes on patient cholesterol levels. In order to determine if following these guidelines helps to reduce overall cholesterol, a total of 18 participants (N = 18) with moderate to high cholesterol ratios (i.e., 3.91 to > 5.0) were recruited for a healthy lifestyle study and their cholesterol ratio was calculated three times over a six week period: Week 0 (baseline), Week 3, and Week 6. Using the variables "Week 0", "Week 3", and "Week 6" in the data set, conduct a One-Way, Within Subjects (AKA Repeated Measures) ANOVA, at α = 0.05, to see if participants cholesterol ratios significantly decrease over the six week period.
Identify the correct written form of the null hypothesis
- A. The mean cholesterol ratio between baseline and week 6 are equal
- B. The mean cholesterol ratio between the three test weeks are NOT equal
- C. The mean cholesterol ratio between baseline and week 6 are NOT equal
- D. The mean cholesterol ratio between the three test weeks are equal
