In this module we will explore the concept of a confidence interval to estimate an unknown population parameter. Specifically, we will obtain confidence interval estimates for unknown population mean and for unknown population proportion. We will also find how large a sample we would require to estimate these parameters for any given amount of accuracy and confidence level.

Learning Objectives:

• Construct and interpret a confidence interval
• Student’s t-distribution
• Standard error and margin of error
• Sample size estimation
