Please answer “True” or “False.” The right-hand side Y (which can be one or more attributes) of a completely non-trivial FD X -> Y cannot be a super key.
Added by Linda C.
Step 1
A functional dependency (FD) is a relationship between two sets of attributes in a relation. X -> Y means that for any two tuples in the relation, if they have the same values for attributes in X, they must have the same values for attributes in Y. A non-trivial Show more…

True or false (Explain why!): When a regression suffers from omitted variable bias, the residuals will not sum to zero.

True or False: The value of $R^{2}$ never decreases as more explanatory variables are added to a regression model.

Determine whether the statement is true or false. If it is true, explain why it is true. If it is false, give an example to show why it is false. If $f_{x}(x, y)$ is defined at $(a, b),$ then $f_{y}(x, y)$ must also be defined at $(a, b)$.
