The regression equation for the given data. To construct: The scatterplot for the variables the average time per day spent for men and the average time per day spent for women with the regression line.
The regression equation for the given data. To construct: The scatterplot for the variables the average time per day spent for men and the average time per day spent for women with the regression line.
Solution Summary: The data shows the average time per day spent for men and women with the regression line. The regression equation is stackrely=-0.059+0.866x.
Definition Definition Representation of the direction and degree of correlation in graphical form. The grouping of points that are plotted makes it a scatter diagram. A line can be drawn showing the relationship based on the direction of points and their distance from each other.

a.
To determine
To find: The regression equation for the given data.
To construct: The scatterplot for the variables the average time per day spent for men and the average time per day spent for women with the regression line.
b.
To determine
To obtain: The predicted value of the women with
x=2.85 hours for men if x is meaningful.
To explain: The reason that the x value is not meaningful.
c.
