Answer 1

z=?z=?0x0.47380.4738

A normal curve is over a horizontal x-axis and is centered on 0. Vertical line segments extend from the curve to the horizontal axis at two points labeled z = ? each. The area under the curve between the left vertical line segment and 0 is shaded and labeled 0.4738. The area under the curve between 0 and the right vertical line segment is shaded and labeled 0.4738.

z1= -1.94   and z2 = 1.94

total shaded area = 2*0.4738. =0.9476
