QuestionThe expected value of random variable a. is the same as the median b. Exists if the random variable is limited c. always exists d. Is well defined if
Studdy Solution
Evaluate option d: "Is well defined if ."
This statement is correct. The expected value is well-defined if the expectation of the absolute value of , , is finite. This condition ensures that the expected value converges.
The correct option is:
