Transcribed Image Text:10. The following table is computed using data from 2012 from the Current Population Survey.
Dependent Variable: Avg Hourly Earnings (AHE)
The data set consists of information on 7440 full-time, full-year workers. The highest educa-

tional achievement for each worker was either a high school diploma or a bachelor's degree. College (X)

The workers' age ranged from 25 to 34 years. The data set also contains information on the

region of the country where the person lived, marital status, and the number of children. For Female (X2)
the purposes of the exercises, let:

(a) Using the regression results in column (1): Compute the 99% confidence interval for the
effect of a gender on earnings. Based on the confidence interval, is there statistically
significant evidence that women's average hourly earning is $4.50 less than men's?
(b) Using the regression results in column (1): Interpret the coefficient on college in words.
(c) Using the regression results in column (1): Does a college education have a statistically
significant effect on earnings? Explain and use the appropriate statistical test to explain
your answer.
(d) We are primarily interested in the effect of a college education on earnings. Provide
an example of a variable that could potentially result in omitted variable bias on our
coefficient of interest. Explain why the variable could result in omitted variable bias
and the direction (positive/negative) and magnitude (overestimate/underestimate) of
the bias.
