Question: #5) Now let's look at the relationship between a husband’s education and his wife’s education separately for couples in which the wife is employed full time (variable wifeft equals 1) and in which the wife is not employed full time (wifeft equals 0).

a. Use the Graphs menu to make the appropriate scatterplot using wifeft as the Set Markers By variable.

b. Edit the chart so that separate regression lines are drawn for the two types of couples. Print separate R2 values as well.

c. Does there seem to be a linear relationship between a husband's and wife's education for both groups of couples? What is the correlation coefficient between a husband's and wife's education for couples in which the wife is employed full time? For couples in which the wife is not employed full time?
