Find the area under the standard normal curve to the right of z=−2.18. Round your answer...

Find the area under the standard normal curve to the right of z=−2.18. Round your answer to four decimal places, if necessary.

In order to find the desired area, we will need to find the area from z to infinity. We can also use the fact that the area from z to infinity is the same as the area from negative infinity to −z−z to find the area. A graphical representation of the problem is shown below.

−404−2.17?

==−4042.170.985

P(−2.17<z<∞)P(−2.17<z<∞)

=P(−∞<z<2.17)=P(−∞<z<2.17)

=0.985
