Question

The values of *z*-score are given.

1a.) Find the area under the normal curve to the right of
*z* = -0.86. Round the answer to four decimal places.

The area under the normal curve to the right of *z* =
-0.86 is ____.

1c.) Find the area under the normal curve between *z* =
-0.32 and *z* = 0.92. Round the answer to four decimal
places.

The area under the normal curve between *z* = -0.32 and
*z* = 0.92 is ____.

1d.) Find the area under the normal curve outside *z* =
-1.52 to *z* = -0.47. Round the answer to four decimal
places.

The area under the normal curve outside *z* = -1.52 to
*z* = -0.47 is ____.

Answer #1

Q.1a) P(Z > -0.86) = P(Z < 0.86) = 0.8051

Therefore, the area under the normal curve to the right of z =
-0.86 is **0.8051**

Q.2a) P(-0.32 < Z < 0.92)

= P(Z < 0.92) - P(Z < -0.32)

= 0.8212 - 0.3745

= 0.4467

Therefore, the area under the normal curve between z = -0.32 and
z = 0.92 is **0.4467**

Q.3a) P(Z < -1.52) + P(Z > -0.47)

= P(Z < -1.52) + P(Z < 0.47)

= 0.0643 + 0.6808

= 0.7451

Therefore, the area under the normal curve outside z = -1.52 to
z = -0.47 is **0.7451**
