Lesson 21. Unit 5. Grade 7 EngageNY

This Problem Set is a part of the Lesson 21, Unit 5, Grade 7. In this lesson, students first consider random samples from two populations that have the same mean. Sampling variability must be considered when deciding if there is evidence that the two population means are actually the same or different, and this idea is developed throughout the exercises. Students then repeat the process by examining two populations that have different means.
