Provide an appropriate response.A set of data consists of the number of years that applicants for foreign service jobs have studied German and the grades that they receive in a proficiency test in that language. The following linear model is obtained: 
where x represents number of years of study and y represents grade in test. What does the slope of the model represent in terms of the grades on the test?
What will be an ideal response?
The slope indicates that grades on the test increase by an estimated 10.9 points for each additional year of study.
