Utilize the data in Table 7-1 on page 119 of your text: 7-1: Calculate the regression equation for the entire range of data. Is this a usable regression line? For full credit for this assignment make sure you have: 1. Found the slope and intercept of the best fit line through Y and X using all 8 data points. 2. Explain the meaning of the slope and intercept. 3. Determine if the model you found is usable under the assumptions of linearity (Suggest you plot a scattergram with a fitted line to make this determination
