• B) \(\frac{s_{\hat{u}}}{\sqrt{\sum_{i=1}^{n}\left(X_{i}-\bar{X}\right)^{2}}}\)

• D) \(\frac { 1 } { n } \times \frac { \frac { 1 } { n - 2 } \sum _ { i = 1 } ^ { n } \left( X _ { i } - \bar { X } \right) ^ { 2 } \hat { u } _ { i } ^ { 2 } } { \left[ \frac { 1 } { n } \sum _ { i = 1 } ^ { n } \left( X _ { i } - \bar { X } \right) ^ { 2 } \right] ^ { 2 } }\)
