Which R code corresponds to graph C?

Question

BlackTom AI · Accepted Answer

The question asks: Which R code corresponds to graph C? The data provided include the question text, an answer field containing the string "2 * (1 - pnorm(2, mean = 0, sd = 1))", and an empty list for answer_options. Because there are no explicit answer choices to analyze, I cannot map a specific option to graph C with certainty. To reason about the code conceptually, recall how the normal CDF and tail probabilities are computed in R: - pnorm(x, mean = 0, sd = 1) gives P(Z ≤ x) for Z ~ N(0,1). - 1 - pnorm(x, mean = 0, sd = 1) gives P(Z > x). - For symmetric two-tailed probabilities, such as P(|Z| > a), you can use 2 * (1 - pnorm(a, mean = 0, sd = 1)) since P(|Z| > a) = P(Z > a) + P(Z < -a) and by symmetry P(Z < -a) = P(Z > a). Now, interpret graph C: the blue shaded area appears to be the tail area(s) beyond a certain threshold on the x-axis (specifically around -2). If graph C shows shading only to the left of -2 (i.e., P(Z ≤ -2) or P(Z < -2)), the corresponding code would be pnorm(-2) (which equals 1 - pnorm(2)). If graph C shows shading on both tails beyond ±2 (i.e., blue on both far left and far right, representing P(|Z| > 2)), then the correct code would be 2 * (1 - pnorm(2)). Since the provided answer options are empty, we cannot definitively declare which code matches graph C. If your intention is to choose between single-tail and two-tail shading, identify whether graph C includes shading only on one tail (left of -2) or both tails (left of -2 and right of 2). Then select: - single-tail (left of -2): pnorm(-2) or 1 - pnorm(2) - two-tail (both sides beyond ±2): 2 * (1 - pnorm(2)) Note: the exact mapping depends on the actual option list, which is not present here. If you can provide the answer_options array, I can map graph C precisely to the correct option and explain each choice in detail.
