Strategic Intervention Material in Statistics and Probability

MODULE 1 Confidence Interval Estimates for the Population Mean

General Learning Competency:
Computes for the confidence interval estimate based on the appropriate form of the estimator for the population mean.

Specific Objectives:
At the end of the lesson, you are expected to:
1. Define confidence level 2. Define confidence interval 3. Compute confidence interval estimate

Introduction:
When we describe population values, we want to be confident about our estimates. Other than the poin estimate, we can use a range of values. This range of values is called interval estimate. You will learn more about estimates in this lesson.

This material helps you to understand confidence interval estimates for the population mean.

We will discuss confidence level and confidence interval. We will also apply the normal curve concepts in computing the confidence interval estimates.
