The data in Table 10.5 consist of simulated ACT scores from 40 participants where 10 
participants were selected from each of four schools. It is assumed that the schools are 
randomly selected from a population of schools in America in order to generalize the 
results found. Two schools (and thus, 20 participants) are randomly assigned to the 
computer-based ACT training program, while the other two schools are randomly assigned to
the standard paper-and-pencil program in order to assess the effectiveness of these 
different types of programs;

*The primary hypothesis of interest is whether the standard paper-and-pencil and 
computer-based ACT training programs differ in effectiveness. The following output 
generates the output to assess this hypothesis. The following SAS syntax is used to obtain  
the mixed model ANOVA on the data in Chapter 10, Table 5;

PROC GLM; 
CLASS a b; 
MODEL act = a b a*b;
