Introduction This site provides illustrative experience in the use of Excel for data summary, presentation, and for other basic statistical analysis.
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.
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. Chapter 8 of the textbook explains how to make inferences from two samples using the process of hypothesis testing. Assume that the two samples are independent simple random samples selected from normally distributed populations.
Do not assume that the population standard deviations are equal.
The goal is that you become familiar with the formal report format that you will use whenever you are reporting statistical analysis. The report format includes the following sections: Abstract, Purpose, Methods, and Results. Assume that you are asked to perform an exploratory data analysis in which the emphasis is to compare the difference between the body mass index BMI values of men and women.
Assume you are a biostatistics analyst and you received a request from the director of the nutrition program to perform the analysis. Because it has been some time since the director has had a statistics course, any points that would make your analysis easier to understand would be appreciated.
Generate appropriate histograms or box plots. Find appropriate statistics that will help to understand the data set. Are there any notable features? Are there any outliers? Describe the key elements of center, variation, distribution, and outliers.The numbers back it up: statistics doesn't have to be hard.

Returns the probability associated with a Student's t-Test. Use TTEST to determine whether two samples are likely to have come from the same two underlying populations that have the same mean.
