The area under the standard normal curve between $z = -1.5$ and $z = 2.5$ can be found by looking up the values in a standard normal distribution table or using a calculator with statistical functions. The area to the left of $z = 2.5$ is approximately 0.9938, and the area to the left of $z = -1.5$ is approximately 0.0668. Subtracting these values gives us the area between these two z-scores: $0.9938 - 0.0668 = 0.9270$.
