Assume the random variable X is normally distributed with mean muequals50 and standard deviation sigmaequals7. Compute the probability. Be sure to draw a normal curve with the area corresponding to the probability shaded. P(54less than or equalsXless than or equals68) Which of the following normal curves corresponds to P(54less than or equalsXless than or equals68)? A. 545068 A normal curve has a horizontal axis with three labeled coordinates, 50, 54, and 68. The curve's peak is near the top of the graph at horizontal coordinate 50. Three vertical line segments run from the horizontal axis to the curve at 50, 54, and 68. The area under the curve between the vertical line segments at 50 and 54 is shaded. B. 545068 A normal curve has a horizontal axis with three labeled coordinates, 50, 54, and 68. The curve's peak is near the top of the graph at horizontal coordinate 50. Three vertical line segments run from the horizontal axis to the curve at 50, 54, and 68. The area under the curve between the vertical line segments at 54 and 68 is shaded. C. 545068 A normal curve has a horizontal axis with three labeled coordinates, 50, 54, and 68. The curve's peak is near the top of the graph at horizontal coordinate 50. Three vertical line segments run from the horizontal axis to the curve at 50, 54, and 68. The area under the curve to the left of the vertical line segment at 54 is shaded. P(54less than or equalsXless than or equals68)equals nothing (Round to four decimal places as needed.)
