ANSWER:
Solution:
Step 1 of 10:
- The claim is to find the area under the standard normal distribution between 0 and 1.50.
We have the z-scores z = 0 and z = 1.50
Then P(0 < z < 1.50) = P(z < 1.50) - P(z < 0)
= -
(In the area under normal curve we have to see in row 1.5 under column 0.00).
(In the area under normal curve we have to see in a row 0.0 under column 0.00).
Then P(0 < z < 1.50) = 0.9332 - 0.5000
= 0.4332.
Hence, P(0 < z < 1.50) = 0.4332.
