You may need to use the appropriate appendix table or technology to answer this question. Suppose we are interested in the Annual Salary of Electronics Associated, Inc. (EAI) managers and we find that for a sample of n = 30 managers, there was 0.5034 probability of obtaining a sample mean within + $500 of the population mean (see the figure below). Sampling distribution of X Of= 730.30 P(51,300 S X S 52,300) The title of the diagram is "Sampling Distribution of x". A bell-shaped curve divided into three areas is above a horizontal axis labeled x. The text Ox = 730.30 is on the figure. . The horizontal axis has three tick marks. In the order they appear, from the left side of the figure to the right, they are: 51,300, 51,800, and 52,300. The label 51,800 is below the maximum point on the curve and in the center of the horizontal axis. The first area under the curve is to the left of 51,300, is shaded, and is labeled P(x
