The set of artificial data shown in Table 6.32 is used in several contexts to provide practice in implementing appropriate analyses for different situations. The use of the same numeric values for the different problems will save computational effort.

Assume that the data represent test scores of samples of students in each of five classes taught by five different instructors. We want to reward instructors whose students have higher test scores.Do the sample results provide evidence to reward one or more of these instructors?

(Write down the appropriate null hypothesis, discuss what statistical tools are used, and provide relevant output from computer software to justify your results.)
