Take a look at the dataset below which reflects the outcome of becoming a great chef. We suspect that variables such as number of years of experience cooking, level of formal culinary education, and number of different positions (sous chef, pasta station, etc.) all contribute to rankings or scores on the Great Chef Test. Use your knowledge of creating equations from data to answer the following questions:

1. 1. Which are the best predictors of a chef's score?
   2. What score can you expect from a person with 12 years of experience and a Level 2 education who has held 5 positions?
