Two schools are investigating whether there is a difference in the proportion of students who attend the homecoming football game. Both schools have over 2,000 students. School A selected a simple random sample of 100 students and found that 98 attended the homecoming football game. School B selected a simple random sample of 150 students and found that 142 attended the
homecoming football game. Let perepresent the combined sample proportion for the two schools, and let ni and Ng represent the respective sample sizes. Have the conditions for statistical
inference for testing a difference in population proportions been met?
