This week we will look at how to test hypotheses and make confidence intervals for categorical data. These are the first two formulas in the inference about proportions section of the Interactive Formula Sheet.
Goal. To introduce the one-sample hypothesis test for proportions.
Step 1. Look at these notes: One sample inference for proportions
Step 2. Try this workshop: Psychic testing
Step 3. Here is a video with my solutions to the workshop, and an explanation of why I'm not really psychic, in case you were wondering: YouTube
Step 4. I've posted the homework for this week. You should try to solve all of the problems by Friday. On Friday, I'll post a form where you can submit some of your solutions online.
Goal. To introduce one-sample confidence intervals for proportions.
Step 1. Try this workshop: Born in Virginia
Step 2. Here are my solutions & comments for the workshop: YouTube
Step 3. Let me know if you have any questions about the workshops or homework. Send me e-mail questions any time. I'm available for Zoom meetings if you need more help.
Goal. Catch-up and review one-sample inference for proportions.
That's it for today! Next week we'll cover two sample inference about proportions.
