Question: This set of questions pertains to variables X and Y (don’t work to hard at this, it can be calculated from the correlation derived in problem 1):

1. Find the slope and intercept for the relationship between variables X and Y (use X as the predictor variable).
2. Find the slope and intercept for X and Y, where Y is the predictor variable.
3. Construct scatterplots, include the regression slopes and intercepts.
4. List the predicted scores and residuals for each subject for problem 5a and 5b.
5. Why are the two slopes different?
6. Find the standard error of estimate for the slope in 5a and 5b.
7. Test the null hypotheses B _YX = 0 and B _XY = 0; assume α = 0.05, two tailed.
8. Test the null hypothesis B ₀ = 0 (for predicting Y from X); assume α = 0.05, one tailed.
9. Write a brief statement summarizing the results from problem 5a and 5h.
10. How do you determine if the test should be B _YX = 0 or B _XY = 0?
