Assume the variable x is normally distributed. Standardized Test Composite Scores 28633Score mu equals 21.3 sigma equals 5.428 less than x less than 33 x A graph titled "Standardized Test Composite Scores" has a horizontal x-axis labeled "Score" from about 2 to 40 with tick marks at 6, 28, and 33. A normal curve labeled μ = 21.3 σ = 5.4 is centered above the x-axis at 21.3. Two vertical line segments extend from the curve to the x-axis at 28 and 33. The area below the curve and between the two vertical line segments is shaded and labeled 28 < x < 33. The probability that the member selected at random is from the shaded area of the graph is nothing . (Round to four decimal places as needed.)
