Choose the correct graph of the sampling distribution below. A. 50.5 53.7 47.3 x overbar A normal curve is over a horizontal x overbar axis labeled from 47.3 to 53.7 in increments of 1.6 and is centered on 50.5. A vertical line segment extends from the horizontal axis to the curve at 50.5. B. 50.5 60.5 40.5 x overbar A normal curve is over a horizontal x overbar axis labeled from 40.5 to 60.5 in increments of 5 and is centered on 50.5. A vertical line segment extends from the horizontal axis to the curve at 50.5. C. 0 2 -2 x overbar
