A report described a survey of parents of children under the age of 18. Each person in a representative sample of 839 working fathers and a sample of 592 working mothers was asked if balancing the responsibilities of a job and a family was difficult. It was reported that 435 of the fathers surveyed and 369 of the mothers surveyed said that it was difficult. The two samples were independently selected and were thought to be representative of working fathers and mothers of children under 18 years old. Use this information to calculate a 95% confidence interval estimate of the difference between the proportion of working fathers who find balancing work and family difficult, P1, and this proportion for working mothers, P2.
