Question

Find the indicated z-score shown in the graph to the right. Area = The z-score is (Round to two decimal places as needed.)

Answer 1

We need to calculate z,

when P(Z <= z) = 0.2514

From the standard normal table we need to look for which value of z the probability value is 0.2514

From standard normal table we get, z = -0.67 (answer: minus 0.67)
