Please note that they have omitted two-sample t test from the Stat 1000 course. That means you should only do the matched pairs section in Lesson 10 of my Basic Stats 1 book. To keep it simple, study up to the end of
question 2 only in Lesson 10.
However, you do have to study the entire Lesson 11: Inference for Proportions.
Did you read my email with the revised 5 steps for testing hypotheses (they have omitted critical values from the hypothesis testing steps)?
