Question

Fact: the region under the standard normal curve that lies to the left of -1.99 has area 0.0232955. Without consulting a table or a calculator giving areas under the standard normal curve, determine the area under the standard normal curve that lies to the right of 1.99. answer: b) Which property of the standard normal curve allowed you to answer part a)? A. The total area under the curve is 1 B. The standard normal curve is symmetric about 0 C. Almost all the area under the standard normal curve lies between -3 and 3 D. The standard normal curve extends indefinitely in both directions E. None of the above

Explanation / Answer

The area that lies to the right of 1.99 will be same as the area that lies to the left of 1.99. Thus the answer is 0.0232955
