OJUS 3312 ANOVA (ANOVA will not be on the exam) Researchers have suggested that females who have more friends are at greater risk for receiving delinquent pressure. To test their notion, you take a random sample of girls and classify them into one of three groups: (1) those who have a lot of friends, (2) those who have some friends, and (3) those who have a few friends. Then, you ask each girl to self-report the number of delinquent offenses her friends had encouraged her to do. Using the 0.05 significance level, test the null hypothesis that there is no difference among the three groups (i.e., the three population means are equal). The following table shows the number of delinquent acts encouraged by friends for each girl in one of the three groups.
