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

You are a member of a population of 10,000 people. You happen to be chosen for a simple random sample of size 1,000 this year. Then you are chosen for another simple random sample of size 100 (drawn independently of the first sample) next year. You think you're incredibly unlucky to be chosen for two such samples, but how unlucky are you? The probability of this happening is which of the following? a. (1/10,000)2 b. 2/10,000 c. 1/10 d. 1/1,000

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...
