- Set up a spreadsheet simulation model in which whether Atlanta wins each game is arandom variable.Some research has shown that older parents are not as strict when disciplining their children compared to younger parents. Children of older parents are more likely to be in daycare and have greater independence than children of younger parents, whereas children of younger parents are more likely to be at home with parents and other siblings, and encounter more home discipline. A researcher observed the disciplinary habits of 456 families with at least one child, categorizing each as "high" or "low" in terms of disciplinary strictness. The families were also divided into older parents (those 29 years of age or younger) and older parents (30 years old and up). Are the following data consistent with the hypothesis that older parents are not as strict when disciplining their children?
