You will complete a paired T-test analysis for this assignment using the data set provided to you.

Module 2 Dataset (Links to an external site.)

A study tested whether cholesterol was reduced after using a certain brand of margarine as part of a low fat, low cholesterol diet. The subjects consumed on average 2.31g of the active ingredient, stanol ester, a day. This data set contains information on 18 people using margarine to reduce cholesterol over three time points. There are two populations, A and B.

You will compare the means in population A pre and post intervention to that of population B pre and post intervention.

The variables you will consider are cholesterol levels and the use of margarine.

You will include a narrative that includes possible hypotheses and null hypotheses, an explanation of the relationship between the variables, and report the important results in APA format.
