Confidence Interval Mathematics & Economics Statistics Project (Statistics Project Sample)
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 SPSS to accomplish the following:
Construct a 99% confidence interval estimate of the mean body mass index for men.
Construct a 99% confidence interval estimate of the mean body mass index for women.
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?
