So here's the plan. I have listed one of every type of probability problem from the text. They are all odd. Show your work. Check your answers. Each number is a different concept—keep each one separate! Here they are:
- Ch. 6 #25a
- Ch. 6 #25bc
- Ch 6 #25e
- Ch. 14 #13a-2
- Ch. 14 #13b-1
- Ch. 14 #13b-4
- Ch. 15 #5b
- Ch. 15 #9d
- Ch. 15 #15a
- Ch. 15 #23
- Ch. 16 #15a
- Ch. 16 #15b (hint: look on P. 311—this is just a boring calculator problem. Another hint: can you find this formula on your formula sheet?)
- Ch. 16 #3
- Ch. 16 #33ab
- Ch. 17 #13d (Hint: This is binomial. Use Binomialpdf in handy stats. Also, there is a formula for this one, can you find it? Can you write it? See the example on P. 321-322)
- Ch. 17 #15ab (Hint: Your formula sheet has these two formulas!)
- Ch. 17 #13a
- Ch. 17 #15c (this problem is optional)
- Ch. 18 #9 (Hint: If this feels like a 1-prop z-test, you're right!)
- Ch. 18 #21cd (Hint: central limit theorem)
WOW! That's a long list. But a lot of the problems are short.
Now do this: go back and put a word or phrase on every problem. If you are going to recognize a problem on the AP test, you have to name it! A problem without a name feels lonely and neglected! Give it an identity! I'll get you started:
- drawing a normal curve
- normalcdf
- inverse normal
- disjoint—or—add
- independent—and—multiply
- at least one = 1 – P(none)
- you do the rest!
