a. Identify the populations and the response variable. b. give I, n, and N. c. give the degrees of freedom of the ANOVA F statistic.
Many states require schoolchildren to take regular statewide tests to assess their progress. Children with learning disabilities who read poorly may not do well on mathematics tests because they can't read the problems. Most states allow "accommodations" for learning-disabled children. Randomly assign 100 learning-disabled children in equal numbers to three types of accommodation and a control group: math problems are read by a teacher, math problems are read by a computer, math problems are read by a computer that also shows a video, and standard test conditions. The researcher would like to compare the mean scores on the state mathematics assessment.
