CorrectNot quiteAnswer A

Correct answer: A

Explanation

  1. The area to the right of 0 is 0.5, and 0.4772 of it lies between 0 and 2.

  2. P(Z>2)=0.5−0.4772=0.0228P(Z > 2) = 0.5 - 0.4772 = 0.0228.

Worth noting

0.5228 takes 0.4772 away from 1, but 0.4772 is measured from 0, not from the far left.
