Homework 1 Review
- Check your feedback!!
- Question 6: regression with age and weight
- The dry weight is our outcome! It is important to always use
Y ~ X in the lm() function!
- Stating the population simple linear regression model = writing it out using \(\beta\)s and stuff
- Question 4: The choice of an alternative hypothesis should depend primarily on (choose all that apply). Explain your reasoning.
- When creating the hypothesis tests, you should not use the data collected to determine the test
- Your alternative should be formed from prior work/research
- Population models should either be written like \(E(Y|X) = \beta_0 + \beta_1 X\) or \(Y = \beta_0 + \beta_1 X + \epsilon\)
Key Dates
- Homework 2 due on Friday!!
