A sociologist is studying the effect of having children within the first two years of marriage on the divorce rate. Using hospital birth records, she selects a random sample of 200 couples that had a child within the first two years of marriage. Following up on these couples, she finds that 80 couples are divorced within five years. Use Scenario 8-4. A 90% confidence interval for the proportionp of all couples that had a child within the first two years of marriage and are divorced within five years is 0.40 + 0.044. a O b 0.40 + 0.004. 0.40 ± 0.057. O d 0.40 + 0.035.
