C. Develop the least squares estimated regression equation. Enter negative value as negative number.
Satisfaction= + Speed (four decimals)
D. Provide an interpretation for the slope of the estimated regression equation.
The slope of the estimated regression line is approximately (to 4 decimals). So, a one unit - Select your answer -increasedecreaseItem 6 in the speed of execution rating will increase the overall satisfaction rating by approximately points (1 decimal)
E. Suppose TD Ameritrade developed new software to increase their speed of execution rating. If the new software is able to increase their speed of execution rating from the current value of 2.8 to the average speed of execution rating for the other 10 brokerage firms that were surveyed, what value would you predict for the overall satisfaction rating?
(to 3 decimals)
