Problem 1


*There is a small rounding error in the work when finding SSE. I used 2.667 for the slope insted of 2.6677... This changes the final answer slightly. The correct answer is 7.7037.

An educator wants to see if there is a relationship between the number of absences for a student and the student’s final grade. Use the data below to find the S2 for the random error of the least squares prediction line:
Absences    10 12   2   0    8   5
Final Grade 70 65 96 94 75 82
