Ans. #1

d
RATIONALE: The constraints, in portfolio selection problems, usually take the form of restrictions on the type of permissible investments, state laws, company policy, maximum permissible risk, and so on.

Ans. #2

c
RATIONALE: The degrees of freedom for this t distribution is n  1 = 23.

Ans. #3

b
RATIONALE: The objective function for portfolio selection problems usually is maximization of expected return or minimization of risk.

Ans. #4

b
RATIONALE: An estimate of a population parameter that provides an interval of values believed to contain the value of the parameter is known as the interval estimate.

Ans. #5

b
RATIONALE: The reduced cost indicates the change in the optimal objective function value that results from changing the right-hand side of the nonnegativity constraint from 0 to 1.
