A normal curve is over a horizontal axis and is centered at 0. Vertical line segments extend from the horizontal axis to the curve at negative t@Sub{0}=negative 2.272, 0 and t@Sub{0}=2.272, where negative t@Sub{0}=negative 2.272 is to the left of 0 and t@Sub{0}=2.272 is to the right of 0. The area under the curve to the left of negative t@Sub{0}=negative 2.272 and to the right of t@Sub{0}=2.272 is shaded.
