Question

find the indicated z - score shown in the graph to the right. area = 0.0274 z =? the z - score is. (round to two decimal places as needed.)

Explanation:

Step1: Use z - table (inverse normal).

We know that the area to the right of the z - score is 0.0274. The area to the left of the z - score is $A = 1 - 0.0274=0.9726$.

Step2: Look up in the standard normal table.

We look for the value 0.9726 in the body of the standard - normal (z -) table. The closest value in the table to 0.9726 gives us the z - score.

Answer:

1.91
