Question

A study of wage differentials in a European country showed a significant difference between men and women, based upon an aggregate value of wage averages for all men and women. One theory stated to explain the differences is that working men in this country have longer tenure (years of experience) at their jobs, compared to the typical woman. Given the following sample and population data, please answer the questions below:

Men N=100 smpl mean =14.9yrs Pop StD =5.2 yrs
Women n=49 smpl mean =10.3yrs pop. StD =3.8yrs

a. What is the point estimate of the working experience differences between men and women?

Answer 1

The point estimate for the difference in working experience between men and women is 4.6 years, calculated by subtracting the average years of experience of women from that of men.

Step-by-step explanation:

The point estimate of the working experience differences between men and women can be calculated by subtracting the sample mean of women's years of experience from the sample mean of men's years of experience. Based on the given data, we have:

• Sample mean for men = 14.9 years
• Sample mean for women = 10.3 years

Therefore, the point estimate of the difference is:

14.9 years (men) - 10.3 years (women) = 4.6 years

This point estimate suggests that, on average, men in this sample have 4.6 more years of work experience than women.
