In a 2012 study, regression analysis was used to explore the possible connection between a firm’s overall employee satisfaction level and the firm’s market based economic value. Suppose the data for the study are given in the table below:
Show the data in a scatter diagram and use the least squares criterion to find the slope (b = ====) and the intercept (a) for the best fitting line. Sketch the least squares line in your scatter diagram. Use the line to predict a company’s economic value index when the company’s employee satisfaction level is 48.
