Average

In mathematics, everyone must have heard the term average in one place or other. Almost all types of calculation require taking out an average. In everyday life, the term is used for denoting a certain amount that can be said to be a typical quantity for multiple people or objects. In other words, if a group of people possesses a certain object, then the average gives us an idea regarding the quantity of the object possessed by each person. However, this is solely based on mathematical calculation. It is important to note that most people will not strictly have the average value in a group.

Question

**Finding the Critical Value for Confidence Interval**

This page will guide you through the process of determining the critical value $ z_c $ necessary for forming a confidence interval at a given level of confidence.

**Problem Statement:**
Find the critical value $ z_c $ necessary to form a confidence interval at the confidence level shown below.

**Given:**
\[ c = 0.81 \]

**Required:**
\[ z_c = \boxed{\phantom{00}} \]

(NOTE: Round to two decimal places as needed.)

To solve this:
1. Identify the confidence level (c) provided in the problem.
2. Use the standard normal distribution (Z-table) to find the critical value $ z_c $ corresponding to the given confidence level.
3. Ensure to round your answer to two decimal places for accuracy.

Let's proceed with the calculation to find the required $ z_c $ value for $ c = 0.81 $.
