A recent report from a health-concerns study indicated that there is strong evidence of a nation's overall health decay if the percent of obese adults exceeds 28%. In addition, if the low-income preschool obesity rate exceeds 13%, there is great concern about long-term health. You are asked to conduct an analysis to determine if the U.S. population exceeds that rate. Your analysis is restricted to those counties in the following states: California, Michigan, Minnesota, and Florida. Conduct your analysis for each state. To do this, you will first need to obtain a subset of the data file using the capabilities of your statistical analysis computer program.
Use the data file Food Nutrition Atlas as the basis for your statistical analysis. Variable descriptions are located in the chapter appendix. Prepare a rigorous analysis and a short statement that reports your statistical results and your conclusions.
