Question

The area under the normal curve between z = 0 and z = 1 is ________________ the area under the normal curve between z = 1 and z = 2.

a) Less than
b) Greater than
c) Equal to
d) A, B, or C above dependent on the value of the mean
e) A, B, or C above dependent on the value of the standard deviation

Answer 1

The area under the normal curve between z = 0 and z = 1 is equal to the area under the normal curve between z = 1 and z = 2.

Step-by-step explanation:

The area under the normal curve between z = 0 and z = 1 is equal to the area under the normal curve between z = 1 and z = 2.

To determine the area under the normal curve, we use a standard normal distribution table or calculator. The area between z = 0 and z = 1 is the same as the area between z = 1 and z = 2 because the normal distribution curve is symmetric.

Therefore, the correct answer choice is c) Equal to.
