Dr. Anakin Goldblum has created a 50-item questionnaire which supposedly measures people's levels of depression consistently over time. With that in mind, doing a regression analysis is necessary to see if the scores are similar in different instances. Here's the data below: Depression Score on 12/17/17 Depression Score on 12/17/18 44 28 11 99 69 55 44 42 42 32 17 95 80 51 42 43 What is SS,? *answer will be in the tenths place
