Refer to Data Set 1 “Body Data” in Appendix B and use the weights of males partitioned into the three different age brackets of 18–25, 26–40, and 41–80. Test the claim that men in those three age brackets have the same mean weight.

Sorting One challenge in this project is identifying the weights of men in the three age brackets. First, use the sort feature of your technology to sort all of the columns using Gender as the basis for sorting. You can then delete all of the rows representing females. Next, sort all of the columns using Age as the basis for sorting. It will then be much easier to identify the weights in the different age brackets.

Data Set 1: Body Data 

Body and exam measurements are from 300 subjects (first five rows shown here). AGE is in years, for GENDER 1 = male and 0 = female, PULSE is pulse rate (beats per minute), SYSTOLIC is systolic blood pressure (mm Hg), DIASTOLIC is diastolic blood pressure (mm Hg), HDL is HDL cholesterol (mg/dL), LDL is LDL cholesterol (mg/dL), WHITE is white blood cell count (1000 cells/mL), RED is red blood cell count (million cells/mL), PLATE is platelet count (1000 cells/mL), WEIGHT is weight (kg), HEIGHT is height (cm), WAIST is waist circumference (cm), ARM CIRC is arm circumference (cm), and BMI is body mass index (kg/m2). Data are from the National Center for Health Statistics.
