Question:

For the data involving regression of DI (Y) on IQ (X) in Problem 4 in Chapter 5, assume that the sample of 17 observations (with the outlier removed) consists of males only. Now suppose that another sample of observations on DI (Y) and IQ (X) has been obtained for 14 females. The information needed to compare the straight-line regression equations for males and females is given in the following table.
For the data involving regression of DI (Y) on IQ

a.-d. Repeat parts (a) through (d) of Problem 1 for the straight-line regressions of DI (Y) on IQ (X) for the two sexes. (Consider two-sided alternatives.)
e. Perform a two-sided test of whether the population correlation coefficients for males and females are equal.
