3719	2	Make a linear regression model for predicting examination marks from attached data using the following variables: year (as a numerical variable), student attendance in lectures, student participation in practical lessons. What mark is expected for a student in the year 2009 if the student did not visit lectures but participated in all practical lessons of his/her nominated student group and in half practical lessons of another group (participation in practical lessons = 150%)? Add the software name you used. Codes for marks are the following: A - 6, B - 5, C - 4, D - 3, E - 2. F - 1, MI - 0.	Open
