Question

Find the area under the standard normal curve between z = -1.15 and z = 1.5, rounding the solution to four decimal places.

Answer 1

The area under the standard normal curve between z = -1.15 and z = 1.5 is approximately 0.8081.

Step-by-step explanation:

To find the area under the standard normal curve between z = -1.15 and z = 1.5, we will use the Z-table. The area to the left of z = -1.15 is 0.1251, and the area to the left of z = 1.5 is 0.9332.

To find the area between these scores, we subtract the smaller area from the larger area: 0.9332 - 0.1251 = 0.8081.
