Description
Instructions
This is much easier, if you use the R Markdown command: you can convert your worksheet to HTML, word or PDF. Your submission should include:
1. The code you used.
2. The output from the code.
3. Your written description of the interpretation of the output.
Problems
1. Summarize the wage, height (both height85 and height81), and sibling variables. Discuss briefly.
2. Create a scatterplot of wages and adult height which excludes the observations with wages above $500 per hour
3. Create a scatterplot of wages and adult height (height85). Discuss any distinctive observations.
4. Create a scatterplot of adult height against adolescent height. Identify the set of observations where people’s adolescent height is less than their adult height. Do you think we should use these observations in any future statistical analysis we conduct with this data? Why or why not?
5. Do children on average have higher education than their father? Test the appropriate hypothesis. Compute and interpret a 95% confidence interval for the difference between father education and child’s education.
6. Is there a relationship between father’s educational attainment and child’s hourly wage? Test the appropriate hypothesis.
7. Test the hypothesis that height influence the average hourly wage. Construct and interpret a 95% confidence interval.
8. What other variables in the dataset do you think may affect usual hourly wage? Describe the relationship you may expect. What statistical tests would you use to determine if these relationships exist?
