Question

Using the standard Normal distribution tables, what is the area under the standard Normal curve corresponding to -0.5 < Z < 1.2?

a) 0.3085
b) 0.8849
c) 0.2915
d) 0.5764

Answer 1

To find the area under the standard Normal curve corresponding to -0.5 < Z < 1.2, we can use the z-table. The area between these two z-scores is 0.5764.

Step-by-step explanation:

To find the area under the standard Normal curve corresponding to -0.5 < Z < 1.2, we can use the z-table. The z-table provides the area to the left of a given z-score. The area to the left of -0.5 is 0.3085, and the area to the left of 1.2 is 0.8849.

To find the area between these two z-scores, we subtract the area to the left of -0.5 from the area to the left of 1.2. The result is 0.8849 - 0.3085 = 0.5764.

Therefore, the correct answer is d) 0.5764.
