Question

Atif has a z score of 1.02 from a converted iq score. from a z table, the percentage between his score and the mean is 34.61%. what percent of people have iqs at or lower than atif's score?

Answer 1

Answer: 84.61%

Explanation.
Refer to the diagram shown below.

When the z-score is z = 0, then the area under the distribution curve is 50%, which corresponds to the mean, μ.

The given z-score is greater than zero, so the shaded area is 34.61%. to the right of z=0
The area to the left of z = 1.02 is 50% + 34.61% = 84.61%.
This percentage represents the people with IQs at or lower than Atfif's score.
