Find the probability that the member selected at random is from the shaded region of the graph. Assume the variable x is normally distributed. Pregnancy Length in a Population of New Mothers 280 238 293 Pregnancy length (in days) mu equals 270sigma equals 12280 less than x less than 293 x A graph titled "Pregnancy Length in a Population of New Mothers" has a horizontal x-axis labeled "Pregnancy length (in days)" from about 228 to 312 with tick marks at 238, 280, and 293. A normal curve labeled = 270 = 12 is centered above the x-axis at 270. Two vertical line segments extend from the curve to the x-axis at 280 and 293. The area below the curve and between the two vertical line segments is shaded and labeled 280 < x < 293.
