Chapter 6 Test
Day 64
Start Here
Questions to be Sure to Include
-
Many of the learning targets can be addressed within a single context. Create a context with a nice probability distribution and you can ask several questions within that context.
-
One contextual question that deals with transforming and combining random variables. I like the temperature conversion from Fahrenheit to Celsius for transforming variables and monthly sales for combining random variables.
-
One question where students have the option of using a binomial distribution or a normal approximation to calculate a probability. Let them choose which approach and give full credit for both approaches (just make sure they check the Large Counts condition if they use the Normal approximation.)
-
One inferential thinking question. So maybe students use the binomial distribution to figure out the probability a free throw shooter makes 9 or more free throws out of 10 and then assess whether this happening would be convincing evidence that a player shoots better than 60%.
-
Don’t be afraid to ask a Chapter 5 probability question on this test if it fits.
-
At least one old AP question. There are many to choose from and they are very accessible for students after completing this chapter.
Tips to Give Your Students
-
Close reading and careful writing are critical to your success this year.
-
Be sure to answer all parts of each question.
-
There are a lot of formulas in this Chapter. Don’t memorize them. Understand them.
-
Don’t use binompdf as your “work” for a free response. Use the binomial formula.
-
Do use binomcdf as your “work” for a free response. Just be sure to identify the distribution as binomial along with the two parameters n and p.
-
Be able to tell when a situation calls for a binomial distribution, a geometric distribution, or a Normal distribution.
