Catherine just graduated and received a Bachelor’s Degree. She wants to determine whether she needs to continue pursuing a Master’s Degree or start working.

She did a study on the monthly income earned by a person based on the number of years they spent studying after high school. The data collected from a sample of 18 are as follows:

Years Income ($) Years Income ($)
