Question

In this​ exercise, you will investigate the relationship between a​ worker's age and earnings.​ (Generally, older workers have more job​ experience, leading to higher productivity and​ earnings.)The following table contains data for​ full-time, full-years​ workers, age​ 25-34, with a high school diploma or​ B.A./B.S. as their highest degree. Download the data from the table by clicking the download table icon A detailed description of the variables used in the data set is available here. Use a statistical package of your choice to answer the following questions.. Suppose you are interested in estimating the following model

Ahe​ = β0 + β1Age + u

Run a regression of average hourly earnings ​(AHE​) on age (Age​). What is the estimated intercept β0​?

The estimated intercept β0 is _____?
