Many Americans spend time worrying about paying their bills. A survey by Fleishman-Hilliard Research for MassMutual discovered that 60% of Americans with kids say that paying bills is a major concern. This proportion compares to 52% of Americans without kids. Suppose 850 Americans with kids and 910 without kids were contacted for this study. Use these data to create a 95% confidence interval to estimate the difference in population proportions between Americans with kids and Americans without kids on this issue.
