Answer 1

The combined area is 0.9545.

Given:

The area under the normal curve to the left of z=-2 plus the area

under the normal curve to the right of z = 2.

Area under the normal curve to the left of z = -2 is:

= 0.0228

Area under the normal curve to the right of z = 2

= 0.9772

Combined area is = 0.9545

Therefore The combined area is 0.9545.
