Question

Determine the following areas under the standard normal (z)

curve. (Round your answers to four decimal places.)
(a) to the right of 0
(b) to the right of −4.5

Answer 1

To find the areas under the standard normal curve to the right of 0 and to the right of -4.5, we can use the z-table.

Step-by-step explanation:

To determine the area under the standard normal curve, we can use the z-table.

(a) To find the area to the right of 0, we subtract the area to the left of 0 from 1. The area to the left of 0 is 0.5, so the area to the right of 0 is 1 - 0.5 = 0.5.

(b) To find the area to the right of -4.5, we subtract the area to the left of -4.5 from 1. Since -4.5 is far in the left tail of the distribution, the area to the left of -4.5 is very close to 0. Therefore, the area to the right of -4.5 is close to 1.
