The probability $P ( - 2.50 < z < 1.50 )$ can be found by looking up the z-scores in the standard normal distribution table or using a calculator. The area to the left of $z = 1.50$ is approximately 0.9332, and the area to the left of $z = -2.50$ is approximately 0.0062. Subtracting these gives $0.9332 - 0.0062 = 0.9270$, which represents the area between $z = -2.50$ and $z = 1.50$.

Use the Standard Normal Distribution to Find P(−2.50<z<1.50).P ( - 2.50 < z < 1.50 ) .P(−2.50<z<1.50).
