Use technology to find the indicated area under the standard Normal curve. Include an appropriately labeled sketch of the Normal curve and shade the appropriate region. a. Find the area in a standard Normal curve to the left of 1.63. b. Find the area in a standard Normal curve to the right of 1.63. Remember that the total area under the curve is 1. a. Which graph below shows the area in a standard Normal curve to the left of 1.63? A. 1.63 A graph contains a Normal curve, plotted over a horizontal axis, which extends between the left and right edges of the graph and has a peak at the horizontal center. Approximately 25% of the way from the graph’s right edge, a vertical line segment with labeled horizontal coordinate 1.63 extends from the horizontal axis to the curve. The area below the curve and to the left of the vertical line segment is shaded. Your answer is correct. B. 1.63…
