(b) Suppose you want to test whether graduates from top 10 universities fare better in the labor market. Propose a regression equation that allows a wage gap between top-10 University graduates (Group 1) and non-top-10 University graduates (Group 2). Define relevant variable(s). Write down the null and alternative hypotheses to test whether the mean log wages differ between the two groups.
(c) Propose a regression equation that allows the return to college education to vary with experience. Write down the null and alternative hypotheses to test whether the return to college education vary with experience.
(d) Propose a regression equation that allows the return to college education to vary with which university you graduate from (that is, whether one belongs to Group 1 or Group 2). Write down the null and alternative hypotheses to test whether the return to college education differ between the two groups.
![1. [Specification] You are interested in returns to college education. You decide to
use log (wage) as the dependent variable, and the main variable of interest is
college education (a dummy variable, taking value 1 if an individual is college
graduate, and 0, otherwise).

you decide to add them in the regression. Propose a population regression
equation to examine the return to college education. Name variables as
you wish. Be careful with notation in your answer; that is, be clear with
whether you use the population regession function or the sample regression
function (or fitted line).
(b) Suppose you want to test whether graduates from top 10 universities fare
better in the labor market. Propose a population regression equation that
allows a wage gap between top-10 University graduates (Group 1) and non-
top-10 University graduates (Group 2). Define relevant variable(s). Write
down the null and alternative hypotheses to test whether the means log
wages differ between the two groups.
(c) Propose a population regression equation that allows the return to college
education to vary with experience. Write down the null and alternative
hypotheses to test whether the returns to college education vary with ex-
perience.
(d) Propose a population regression that allows the return to experience to
vary with the level of experience. Write down the null and alternative
hypotheses to test whether the returns to experience vary with the level
of experience.
(e) Propose a population regression equation that allows the return to col-
lege education to vary with which university you graduate from (that is,
whether one belongs to Group 1 or Group 2). Write down the null and al-
ternative hypotheses to test whether the return to college education differ
between the two groups.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fc1bf6a16-4a30-4d6b-90b1-d3579d3b58f1%2F88f1e5e5-001c-487c-8aef-1779dc0d6cda%2F59pk9g_processed.png&w=3840&q=75)
