Use the following information for problems
To determine what affects turnover rate, a sample of 33 companies was randomly selected and data collected on the average annual bonus and turnover rate (%). In addition, a questionnaire was administered to the employees of each company to arrive at a trust index (measured on a scale of 0 - 100). Below are the multiple regression results. Dependent Variable is Turnover Rate
