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.
- Construct a 95% confidence interval for the difference between the two population proportions.
__________________
- Using the 2% significance level, can you conclude that the two population proportions are different? Use the p-value approach.

What benefits result from the outsourcing of skilled white
collar jobs to developing nations? o Who are the losers? o Will
developed nations like the US suffer from the loss of skilled and
high paying jobs to developing nations? Is there a difference
between the transference of high-paying white collar jobs, such as
computer programming and accounting to developing nations and
low-paying bluecollar jobs? o If so, what is the difference, and
should government do anything to stop the flow...

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?

. Is there a difference between the transference of high-paying
white-collar jobs, such as computer programming and accounting, to
developing nations, and low-paying blue-collar jobs? If so, what is
the difference, and should the government do anything to stop the
flow of white-collar jobs out of the country to countries such as
India?

455 jobs.
For the white-collar positions, 200 males and 200 females
applied. Of the females who applied, 20% were hired, while only 15%
of the males were hired.
Of the 400 males applying for blue-collar positions, 75% were
hired while 85% of the 100 females who applied were hired.
How does looking at the white-collar and blue collar positions
separately suggest a preference for hiring women?

The polling organization Ipsos conducted telephone surveys in
