Using Duncan’s regression of occupational prestige on income and education, and performing the necessary calculations, verify that the omnibus null hypothesis H0:

β1 ¼ β2 ¼ 0 can be tested as a general linear hypothesis, using the hypothesis matrix L ¼ 010 001 $ %

and right-hand-side vector c¼ ½0; 0%

0

. Then verify that the H0: β1 ¼ β2 can be tested using L ¼ ½0; 1; (1% and c ¼ ½0%. (Cf. Exercise 6.7.)
