Solution

Solution Steps

Step 1: Understanding the Problem

We need to find the z-score that corresponds to a cumulative area of $0.1142$ in the standard normal distribution. The z-score indicates how many standard deviations a value is from the mean.

Step 2: Finding the Z-Score

Using the cumulative area $P(Z < z) = 0.1142$ , we can find the corresponding z-score using the inverse of the cumulative distribution function (CDF) for the standard normal distribution.
