# BIO-500 Week 4 Assignment Confidence Interval

Max Points: 30

Details:

In the Topic 1 Assignment, you compared the BMI values from Data Set 1 (in the appendix of the textbook) from a perspective of measuring the center and variation of the data. Chapters 5 and 6 in the textbook allow you to use more sophisticated tools to estimate the parameters of a population.

Refer to Data Set 1 in Appendix B and use the sample data with Excel and/or SAS to accomplish the following:

1. Construct a 99% confidence interval estimate of the mean body mass index for men.

2. Construct a 99% confidence interval estimate of the mean body mass index for women.

3. Compare and interpret the results. It is known that men have a mean weight that is greater than the mean weight for women, and the mean height of men is greater than the mean height of women. Do men also have a mean body mass index that is greater than the mean body mass index of women?

APA format is not required, but solid academic writing is expected.

This assignment uses a grading rubric. Instructors will be using the rubric to grade the assignment; therefore, students should review the rubric prior to beginning the assignment to become familiar with the assignment criteria and expectations for successful completion of the assignment.

You are not required to submit this assignment to Turnitin, unless otherwise directed by your instructor. If so directed, refer to the Student Success Center for directions. Only Word documents can be submitted to Turnitin.
