Bernard Haldane Associates conducted a survey in March 2004 of 1021 workers who held white-collar jobs but who had changed jobs in the previous twelve months. Of these workers, 56% of the men and 35% of the women were paid more in their new positions when they changed jobs. Suppose that these percentages are based on random samples of 510 men and 511 women white-collar workers.

  1. Construct a 95% confidence interval for the difference between the two population proportions.

Flexible work family policies are available to some workers (primarily white collar workers) but not others (blue or pink collar workers). Moreover, female workers are more likely to utilize such policies than men. How does the fact that not all workers have access to such policies perpetuate inequalities in labor market outcomes? How might more equitable use of these policies be encouraged?
