Question

use the table below to find the percentage of data items in a normal distribution that lie between z = - 2.1 and z = - 0.4. click the icon to view the table. the percentage of data items in a normal distribution that lie between z = - 2.1 and z = - 0.4 is %.(type an integer or a decimal.)

Explanation:

Step1: Find area for z = - 0.4

Look up the z - score of - 0.4 in the standard normal distribution table. The area to the left of z=-0.4 is 0.3446.

Step2: Find area for z = - 2.1

Look up the z - score of - 2.1 in the standard normal distribution table. The area to the left of z = - 2.1 is 0.0179.

Step3: Calculate the difference

To find the area between z=-2.1 and z = - 0.4, subtract the area to the left of z=-2.1 from the area to the left of z=-0.4. So, 0.3446−0.0179 = 0.3267.

Answer:

32.67
