Question

What is the the area under the standard normal curve between z = -2.49 and z = -0.57?

Answer 1

Area in between `[z=-2.49]` and `[z=-0.57]`=0.2779

Explanation:

Look at the diagram

Area in between `[z=-2.49]` and `[z=-0.57]`= [Area in between `[z=0]` and `[z=-2.49]`] - [Area in between `[z=0]` and `[z=-0.57]`]

`= 0.4936-0.2157=0.2779`
