review problems: 1 for creating confidence intervals around a mean with standard deviation unknown; 1 for creating confidence intervals around a population proportion; 2 for hypothesis testing of a mean

This learning resource provides an in-depth exploration of statistical inference, focusing specifically on confidence intervals and hypothesis testing. It covers the key formulas for both means and proportions, detailing the conditions necessary for their application. The resource includes a flowchart to help select the appropriate method based on the type of data (categorical or quantitative). Several worked examples illustrate the calculations involved in constructing confidence intervals for unknown population standard deviations using the t-distribution and for known proportions using the z-distribution. The document also includes exercises that encourage practice with real-world scenarios, allowing students to apply their knowledge of confidence intervals and hypothesis tests. Additionally, it emphasizes the interpretation of results and common errors, fostering a deeper understanding of statistical reasoning and evaluation. Through reflection questions, students are prompted to consider the implications of their findings and the relationship between confidence intervals and hypothesis tests.
