I have tried all the problems but the most problems I am not sure how to answer. I will need some help on 11 b., 11 e., and all of 12. for 12 d., I got -57.9 but I am not sure how to interpret.

12 a. I said "No because there is a leftover curved pattern. 12 b. I said "It means when using the lease square regression line with x to predict y will typically be off by about 23. 12 c. I said "-1.993, for every lunch, it will be decreased by -1.993 12 d. I said -57.9. enter image description here
