3.14. Table 3-6 gives data on X (net profits after tax in U.S. manufacturing industries [$, in millions]) and Y (cash dividend paid quarterly in manufacturing industries [$, in millions]) for years 1974 to 1986.
What relationship, if any, do you expect between cash dividend and after-tax profits?
Plot the scattergram between Y and X.
Does the scattergram support your expectations in part (a)?
If so, do an OLS regression of Y on X and obtain the usual statistics.
Establish a 99% confidence interval for the true slope and test the hypothesis that the true slope coefficient is zero; that is, there is no relationship between dividend and the after-tax profit.
