Write out the regression formula based on the results from #5. Predicted Y = a + bX Predicted Y = 7. Calculate the predicted salaries based on the following GPA scores: 1.00 and 9.00 Predicted Y = Predicted Y = 8. Copy the scatterplot from the correlation section and paste (or draw) here. Plot the two dots that will help draw the regression line... Dot 1 ... X = 1 and Y = the first predicted Y value you calculated in #7 Dot 2 ... X = 9 and Y = the second predicted Y value you calculated in #7 Draw a line connecting those two dots. THAT is your regression line that allows you to predict scores. Remember to correctly label each axis. 9. What would the predicted concentration level if consuming 3 sweets? What would the predicted concentration level if consuming 7 sweets? Just for fun (and practice): What would the predicted concentration be for 5 sweets? 10. Figure the standardized regression coefficient
