Quizplus · Accepted Answer

We need to standardize the random variable X as follows:
Z = (X - μ) / (σ / √n)
Where μ = 400, σ = 200, and n = 100.
Substituting the values, we get:
Z = (402 - 400) / (200 / √100) = 0.1
Using a standard normal table, we can find the probability as follows:
P(Z < 0.1) = 0.5398
Therefore, the answer is C.
