q1. Find the area under the Standard Normal Curve in-between z =
-0.63 and z = 0.47
Use the Normal table and give answer using 4 decimal places.
q2. Find the area under the Standard Normal Curve in-between z =
-1.19 and z = 0.36
Use the Normal table and give answer using 4 decimal places.
q3. Find P(z < 1.72)
Use the Normal table and give answer using 4 decimal places.
q4. Find P(z > -2.62)
Use the Normal table and give answer using 4 decimal places.
Solution,
Using standard normal table,
1) P( -0.63 < Z < 0.47)
= P( Z < 0.47) - P( Z < -0.63)
= 0.6808 - 0.2643
= 0.4165
2) P( -1.19 < Z < 0.36)
= P( Z < 0.36) - P( Z < -1.19)
= 0.6406 - 0.1170
= 0.5236
3) P( Z < 1.72)
= 0.9573
4) P(Z > -2.62)
= 1 - P( Z < -2.62)
= 1 - 0.0044
= 0.9956
