If you have been asked to sample 60 people from a chosen population for an observational study. You need to ask a question that separates the sample into two groups, so that you can compare results of another question across the two groups. Therefore, your survey will only be two questions: two numerical data questions or one numerical and one categorical question.
Homework Answers

12 points) While obesity is measured based on body fat percentage (more than 35% body fat for women and more than 25% for men), precisely measuring body fat percentage is difficult. Body mass index (BMI), calculated as the ratio weightheight2weightheight2 is often used as an alternative indicator for obesity. A common criticism of BMI is that it assumes the same relative body fat percentage regardless of age, sex, or ethnicity. In order to determine how useful BMI is for predicting...
