Quizplus · Accepted Answer

The area under the standard normal curve between z = 1.5 and z = 2.5 is found by subtracting the cumulative area up to z = 1.5 from the cumulative area up to z = 2.5. Using standard normal distribution tables or a calculator, the area up to z = 1.5 is approximately 0.9332 and the area up to z = 2.5 is approximately 0.9938. Subtracting these gives 0.9938 - 0.9332 = 0.0606.
