CO C - Calculate and interpret a confidence interval to estimate an unknown population parameter.

CO F - Evaluate the application of statistical analyses in the real world.

Our key concepts for this week include:

• Discuss the impact of having a known or unknown population standard deviation.
• Explain sample size determination for the mean and for the proportion.
• Define the level of confidence.
• Explain the estimation process, including both point and interval estimates.
• Assess the role of descriptive statistics in real world situations.
