We worked on problems from the College Board website to do with two-way tables and tests for independence and homogeneity.

Used the College Board website to become more familiar with the AP requirements. Watched hypothesis testing videos on the College Board site. Attempted some problems.

Two-way tables and chi-squared tests for homogeneity and independence-

Test statistics for one-way tables. The chi-square statistic- Degrees of freedom- The p-value for the chi-square statistic- The goodness of fit test-

Means and standard deviation (standard error) for two proportions - Confidence intervals for two proportions - Number of samples required for a given margin of error -

Further examples of one- and two-sided tests- Setting up the hypothesis- Computing the test statistic- Calculating the p-value and making a decision-

Examples of hypothesis tests- Computing critical values and evaluating critical regions for one- and two-sided tests-

Continuation of discussion on confidence intervals- Introduction to hypotheses- The null and the alternative hypotheses- One-sided and two-sided alternatives- Evaluation with p-values- Decision errors- Type I and Type II errors.

Margin of error and critical values.

Estimating unknown parameters, point estimates and their variability- The standard error- Properties of point estimates- Confidence intervals- Constructing an interval-
