1. Draw a scatter plot for this data. Treat the ACT scores as the explanatory (x) variable. Include a trend line. scatter plot y = 0.0991x + 0.5826 R' = 0.6785 College GPAs 5 10 15 20 25 30 35 40 ACT scores 2. Is there a linear relation between ACT scores and college GPAs? That is, is the correlation statistically significant? (Compare your correlation to Table II.) Be sure you include both the correlation and the value from Table II in your answer to this question. 3. Find the least squares regression line for predicting GPAs treating the ACT scores as the explanatory (x) variable and the GPA as the response variable. 4. Is it appropriate to interpret the intercept? If so, what is the interpretation? Is it appropriate to interpret the slope? If so, what is the interpretation? 5. Predict the GPA of a student whose ACT score was 25. Show how you arrived at this prediction
