You decide to conduct the analytical comparison of Induction vs. Power assertion. In conducting this analytical comparison, how should the null and alternative hypotheses be stated?
One part of raising children is having to discipline them. Hoffman (1963) described three common discipline methods used by parents: power assertion (use of punishment, force, taking away of privileges or possessions), love withdrawal (ignoring or refusing to speak to the child, explicitly stating a dislike for the child), and induction (reasoning with the child, communicating standards of behavior). Barnett, Quackenbush, and Sinisi (1996) noted that little attention had been given to children’s preferences for these different methods. From reviewing the literature, they hypothesized children express a greater preference for induction than power assertion, which in turn is preferred over love withdrawal.
They collected data from a sample of middle school students. Each student watched a videotape of a parent disciplining a child using one of the three forms of discipline. After viewing the videotape, each student rated the effectiveness of the discipline on a 1 to 5 scale, where 1 = “Not at all effective” and 5 = “Very effective”. The results of their analyses are presented below:
a. H0: all ?s are not equal; H1: not all ?s are equal
b. H1: ?Induction = ?Power assertion; H1: ?Induction ? ?Power assertion
c. H0: 1 ? 2; H1: 1 = 2
d. 
b. H1: ?Induction = ?Power assertion; H1: ?Induction ? ?Power assertion
