Suppose one student, called A, missed final exam. According to the policy, his/her score in final is zero. This policy, from statistics point of view, is not so reasonable. So, we use regression analysis to estimate A's final score. Suppose there are total 19 students included A. From 18 students record, we find final score (Y) is related with score of exam 2 (X). From computer, we find the relationship is, Y-3.22+0.84*X, and SSR-1124, SSE-779. Can we use this formula to estimate A's final score? OYes, since F-value is small O Yes, since F-value is big O No, since F-value is big No, since F-value is small
