Applications using Sample Proportions Preview CT-STEM

Reminder about the need to collect and analyze statistics

Here's the real values for p₁ and p₂.

p₁=0.3057

p₂=0.17

Questions

Please answer the questions below.

Question 8.1

Calculate the value of \(p_1 - p_2\)

Question 8.2

Explain what this difference in proportions means in real life, in a way that any high school student could understand.

Question 8.3

How close was your estimate based on random sampling?

Question 8.4

We've been pretending that we didn't have all of the data, so we had to use random sampling in order to estimate our population proportions. Explain why in real life we would NEED to use random sampling to do a similar analysis in a different situation.

Question 8.5

Based on this data it seems that black drivers are disproportionately pulled over in Evanston. How do you feel about that?

Question 8.6

What additional data could we use to explore this issue more deeply?
and/Or
What are some things that we could do to begin to address this?
and/Or
What are some other questions that we could investigate using this (or other) data?
