Chapter 6: Inference for Categorical Data (Weeks 4-6)
Please read Section 6.1 of the textbook. Use the calculator tutorials to learn how to carry out 1-proportion z-interval and z-test on the calculator. Use these slides or the corresponding video to review the concepts or to refer back to when doing the homework questions.
Note: the first half of this video covers 6.1; the second half covers 6.2 inference for two proportions. Also, you will not be required to know how to use tables or R software -- only the TI is necessary.
