Does the number of years that a woman is on birth control (X) have an effect on how long it takes for her to become pregnant (Y) once she ceases to use it and tries to have children? A curious researcher collected the following data for a sample of pregnant women who had previously used birth control:

a. Draw a scatter plot of the data.
b. Calculate the regression slope and Y-intercept.
c. Draw the regression line on the scatter plot.
d. Can you predict how long it will take for a woman who was on birth control for 8 years to get pregnant once she stops using it?
e. Find the coefficients of determination and non-determination. What do they mean?
