Question

find the area under the standard normal curve that lies between the following z-values. round the answers to four decimal places.
part 1 of 2
(a) find the area under the standard normal curve that lies between z = -2.32 and z = -0.82.
the area between z = -2.32 and z = -0.82 is 0.1959.
part: 1 / 2
part 2 of 2
(b) find the area under the standard normal curve that lies between z = -1.71 and z = 1.25.
the area between z = -1.71 and z = 1.25 is

Explanation:

Step1: Find area left of \( z = 1.25 \)

Using standard normal table, \( P(Z < 1.25) = 0.8944 \).

Step2: Find area left of \( z = -1.71 \)

Using standard normal table, \( P(Z < -1.71) = 0.0436 \).

Step3: Subtract to find area between

Area between \( z = -1.71 \) and \( z = 1.25 \) is \( 0.8944 - 0.0436 = 0.8508 \).

Answer:

0.8508
