Quizplus · Accepted Answer

The area under the standard normal curve between z = 0.5 and z = 2.8 is found by subtracting the cumulative probability at z = 0.5 from the cumulative probability at z = 2.8. The cumulative probability at z = 0.5 is approximately 0.6915, and at z = 2.8 is approximately 0.9974. Thus, the area is 0.9974 - 0.6915 = 0.3060.
