(Round to two decimal places as needed.)
Solution
Solution Steps
Step 1: Understand the Problem
The problem requires finding the z-score for a given area under the standard normal distribution curve. The area to the left of the z-score is 0.7734.
Step 2: Use the Standard Normal Distribution Table
To find the z-score corresponding to an area of 0.7734, we need to look up this value in the standard normal distribution table (z-table). The z-table provides the area to the left of a given z-score.
Step 3: Locate the Area in the Z-Table
Search the z-table for the closest value to 0.7734. The closest value is 0.7734 itself, which corresponds to a z-score of approximately 0.75.
