A researcher has designed the relationship between the salaries of 100 selected employees of an organization (shown as "EARN" in $/hour) and their years of education (shown as "YRSEDUC", in years) using the following regression equation:

EARN(i) = B(0) + B(1) YRSEDUC(i) + u(i)

By applying this model on a database, the researcher found that the GRETL result shows the intercept coefficient of the regression line as B(0) = 6.78.

Using the above findings to answer the following questions:

A-Interpret the intercept of this regression.

B-What is the unit of intercept in this regression?
