Suppose a researcher estimates two regressions. Regression 1 is: Y: = 51 + 5212: + 53353: + u: and its residual sum of squares is R351 and its R-squared is Rf. Regression 2 is: )'r = 31 + 5212: + "r and its residual sum of squares is R553 and its R-squared is Rg'. It is the case that: Select one: o A. R881 5 R882 and R212 R22 0 B. R8815 R882 and R215 R22 0 0. R881 :2 R882 and R215 R22 0 D. R881 .2 R882 and R212 R22
