Find the area under the standard curve between Z = 0.12 and Z = 1.93 a. 0.4254 b. 0.4081 c. 0.4172 d. 0.0243
The area under the standard curve between Z = 0.12 and Z = 1.93 is calculated using an excel formula for normal distribution which is =NORM.S.DIST(1.93, TRUE)-NORM.S.DIST(0.12, TRUE).
This results in P(0.12<X<1.93) = 0.9732 - 0.5478 = 0.4254.
This can be calculated using the Z table shown below:
