Test corrections - if you did not get 100% correct the problems you missed. Explain your solutions.
The solutions are on google classroom.
Turn in the corrections. You will get half of the point you missed back.
Define the vocabulary for Ch 8 on Google Classroom
Objectives
- Determine the point estimate and margin of error from a confidence interval.
- Interpret a confidence interval in context.
- Interpret a confidence level in context.
- Describe how the sample size and confidence level affect the length of a confidence interval.
- Explain how practical issues like nonresponse, undercoverage, and response bias can affect the interpretation of a confidence interval.
Agenda

When it asks you to sketch, do that on your own paper, you do not have to turn that in. You can just type the numbers that will be on the x-axis, without the normal curve above.
