Find the standard normal area for each of the following (Round your answers to 4 decimal places.): |
Standard normal area | ||
a. | P(1.22 < Z < 2.12) | |
b. | P(2.01 < Z < 3.01) | |
c. | P(-2.01 < Z < 2.01) | |
d. | P(Z > 0.51) | |
a)
P( 1.22 < Z < 2.12) = P( Z < 2.12 ) - P( Z < 1.22)
= 0.983 - 0.8888
= 0.0942
b)
P( 2.01 < Z < 3.01) = P( Z < 3.01) - P( Z < 2.01)
= 0.9987 - 0.9778
= 0.0209
c)
P( -2.01 < Z < 2.01) = P( Z < 2.01) - p( Z < -2.01)
= 0.9778 - ( 1 - 0.9778)
= 0.9556
d)
P( Z > 0.51) = 1 - P( Z < 0.51)
= 1 - 0.6950
= 0.3050
