find the z - score such that the area under the standard normal curve to the right is 0.11. the approximate z - score that corresponds to a right tail area of 0.11 is (round to two decimal places as needed.)

find the z - score such that the area under the standard normal curve to the right is 0.11. the approximate z - score that corresponds to a right tail area of 0.11 is (round to two decimal places as needed.)

Answer

Explanation:

Step1: Use the property of the standard normal curve

The total area under the standard normal curve is (1). If the area to the right of (z) is (A = 0.11), then the area to the left of (z) is (P(Z<z)=1 - 0.11=0.89).

Step2: Look up the (z) - value in the standard normal table

We look for the value closest to (0.89) in the body of the standard - normal table (the (z) - table). Looking at the standard normal table: The value (0.8888) corresponds to (z = 1.22) and the value (0.8907) corresponds to (z = 1.23). Since (0.89) is closer to (0.8907) than to (0.8888).

Answer:

(1.23)
