1. Develop the least squares estimated regression equation.
2. At 95% confidence, perform a t test and determine whether or not the slope is significantly different from zero.
3. Compute the coefficient of determination. What is your interpretation?
4. Are there violations of the regression assumptions? Are there outliers? Use plots to evaluate these questions. How did you reach your conclusions?
Compute z values for each and comment on your findings.
