1. The T-test Assignment will be graded on accurately completing a t-test using a specified data source. In addition to this, you are expected to analyze the results of the data, correctly report this information, and speak of the significance of findings in terms of public health. The quality of self-assessment, use of citations, use of Standard English grammar, sentence structure, and overall organization based on the required components as summarized in the directions and grading criteria/rubric will be evaluated.
2. Create your product using Microsoft Word, which is the required format for this assignment. Place output from SPSS into this word document as an appendix.
3. Follow the directions and grading criteria closely. Any questions about this paper may be posted in the Q&A Forum.
4. The length of this assignment is to be no less than 3 and no greater than 6 pages, excluding title and reference pages.

T-tests are used when the test statistic follows a normal distribution. It can be used to determine if the means of two sets of data are significantly different from each other.

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

Module 2 DatasetLinks 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 2.31 g 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 population A before margarine use vs. population A after 4 weeks margarine use; compare population A before margarine use vs. population A after 8 weeks margarine use.
• 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
