It is generally believed that children brought up in stable families tend to do well in school. To verify such a belief, a social scientist examined 290 randomly selected students’ records in a public high school and noted each student’s family structure and academic status four years after entering high school. The results are given in the table provided. ACADEMIC STATUS FAMILY STRUCTURE Successfully graduated Did not Graduate Total Guardians 18 31 49 Single parent 101 44 145 Both parents 70 26 96 Total 189 101 290 Test, at the 1% level of significance, whether there is sufficient evidence in the data to conclude that family structure matters in school performance of the students
