For the 2 problems below, find the following: a. Develop the Scatter Diagram for these data b. What does the scatter diagram developed in part (a) indicate about the relationship between the two variables? c. Develop the estimated regression equation by using the formula for computing the values for bo and b1. d. Use the estimated equation to predict the value of y when x=4. e. Compute SSE, SST, and SSR using both set of formula given in the class (They are called Definitional and Computing formula). f. Compute the coefficient of determination r (The same as R ). Comment on the goodness of fit (That is, what does the value of r tell you about the goodness of the fit). Explain why. g. Compute the sample correlation coefficient. h. Determine if the slope is significant at Alpha = 0.05
