Question

use the standard normal table or technology to find the z - score that corresponds to the following cumulative area. 0.952 the cumulative area corresponds to the z - score of . (round to three decimal places as needed.)

Explanation:

Step1: Use standard - normal table

Look up the cumulative area of 0.952 in the standard - normal table (the body of the table which gives the cumulative probability from the left - hand side for a standard normal distribution $Z\sim N(0,1)$).

Step2: Find the z - score

Search for the value closest to 0.952 in the body of the table. The closest value to 0.952 in the standard - normal table gives a z - score. Using the table or a calculator with a normal - distribution function (e.g., in TI - 84 Plus: invNorm(0.952,0,1)), we find the z - score.
