Lesson review:

• the sample mean vs population mean
• sample size vs population size
• interpretation of the slope and y-intercept
• confidence interval = (average-margin of error) to (average-margin of error)
• the margin of error depends on a) sample size and b) variability in the data
• standard deviation
• association (correlation)≠ causation
• random assignment

Homework:

1. Finish Chapter Exercise Page 243-248
2. Finish the Google Form (SAT Math Practice: Statistics) if you didn’t have a chance to do it last week.
3. Review and prepare for our final exam on 6/14 🙂

Feel free to let me know which questions (in previous chapters are OK), and I will explain those in class:)
