Question

use the standard normal table or technology to find the z - score that corresponds to the cumulative area 0.0055. z = □ (type an integer or decimal rounded to two decimal places as needed.)

Explanation:

Step1: Use standard normal table

Look up the cumulative - area 0.0055 in the standard normal table (the z - table). The standard normal table gives the cumulative area to the left of the z - score.

Step2: Find the z - score

Searching the body of the standard normal table for the value closest to 0.0055. The closest value in the table gives a z - score. Looking up the value in the table, we find that the z - score corresponding to a cumulative area of 0.0055 is approximately - 2.54.

Answer:

• 2.54
