Quizplus · Accepted Answer

The expected value of a random variable is denoted by E(X) and is equal to the population mean (μ) when dealing with a population or sample mean (x̄) when dealing with a sample. The option D (F1F1F1S1F1F1F10) represents the population mean, which is the expected value of the random variable. Therefore, option D is the best choice.
