Re-quiz tomorrow · Jan 27, 02:29 PM
I’ll quiz today’s material again tomorrow. I’ve prepared an answer key which I need to scan and upload. It will be available after 3:30.
To prepare, most of you should focus on two things:
1. picking up easy points like “defining variables” and “answering in context.” I graded the first question as follows:
| Define variables | Calculate | Check conditions and assumptions | Answer in context | TOTAL |
|---|---|---|---|---|
| 1 | 4 | 1 | 2 | 8 |
2. recognizing the difference between rescaling one random variable and combining random variables that happen to have the same mean and standard deviation.
