A university research team was studying the relationship between idea generation by groups with and without a moderator. For a random sample of 4 groups with a moderator, the mean number of ideas generated per group was 78, and the standard deviation was 24.4. For a random sample of 4 groups without a moderator, the mean number of ideas generated was 63.5, and the standard deviation was 22. Test the assumption that the 2 population variances were equal against the alternative that the population variance is higher for groups with a moderator.
