2. Lesson 8.2.2 Random Samples
- Objective: I will use random sampling to make a generalization about a population.
- Problem 41: Every member of your team INDIVIDUALLY samples 10 "robins" and finds the mean of their own sample.
- Record your mean in the Form on Google Classroom
- STOPLIGHT (you may work on homework while waiting for all students to finish)
- Problem 42 as individuals (you may use Desmos to construct your box plot/histogram)
- Problem 43 in teams
Homework: Lesson 8.2.2 R/P
