Find the area under the normal curve with mean 0 and variance 1 that l

1.	Find the area under the normal curve with mean 0 and variance 1 that lies between (-1.64) and 1.64.
Answer» Here z~N(0, 1) ∴ p[-1 .64 < Z < 1.64] = Area from 0 to (-1.64) + area from 0 to 1.64 ∴ From the table = 0.4495 + 0.4495 = 0.899.

Find the area under the normal curve with mean 0 and variance 1 that lies between (-1.64) and 1.64.

Answer»

Here z~N(0, 1)

∴ p[-1 .64 < Z < 1.64]

= Area from 0 to (-1.64) + area from 0 to 1.64

∴ From the table = 0.4495 + 0.4495

= 0.899.
