2019 AP Statistics #5 - FRQ Solution - Released Free Response Question - Probability Expected Value
This video is my attempt at the 2019 AP Statistics Free Response problem #5. You can buy a Normal Distribution Rubber Stamp here: amzn.to/2Ek3etd (it's a great gift for a statistics teacher).
This problem required you to understand how to calculate probabilities with the normal distribution and use areas to find cut off values. You are also required to calculate an expected value.
If like my explanations in this video, you might like my AP Statistics Practice Book. It has 100 problems (all with CZcams videos) and is available on Amazon: amzn.to/2LidOCW
Many students and entire classes used the book to prepare for the exam. If you are an AP statistics teacher, email me and I will send you a free copy of the book to check out.

THANK YOU
شكرا يا أستاذ تحية من شمال أفريقيا 😄
IQR is simply Q3-Q1?
thanks!
Bro this saved me thank you so much 9 years later and still useful!
arent the left hands not independent as they cannot be replaced thus the sample changes after each kid selected? we would have have to test 10 percent right
A few days prior to my test and I’m just now finding this incredible resource, thank you so much
I want you
we know the standart deviation why you're using T-distribution
Thank you
THANK YOU
the craziest example ever if you're going to mix a MEAN base data for MEDIAN nope
😘😘😘😘😘😘😘😘😘😘super and easy
Thank you
Thank you! This was incredibly helpful and a really good summary :)

thank you for helping me
Thank you
What is form /shape of this ?
Never clearly understood boxplots until today. Made it easy to grasp.
this helped so much!

Thank you so much for showing how to delete individual list number.
Amazing man
I grade AP Stats exams. You've got one major problem here: students need to know how much information to put down in order to get credit for work. If they draw a good picture, they'd probably be ok, but it would be GREAT for them to write instead: "normcdf(Left bound = 204, Right bound = infinity, mean = 200, SD = 3.5)" with the answer. Students need to label your "calculator speak" so the reader knows what the different numbers mean, and in your case the "work shown" (not counting the picture) would give the student an Incorrect. If students are really good with clear pictures, they can communicate the same info and be ok, but I find in grading these that students are inconsistent.
Thank you man
and nobody tells you why its 1.5 * IQR .. why not 1.25?
Do you have these methods for excel ?
Thank you for this amazing video
i needed this, thanks boss.
how about aX+bY, if X~N and Y~N?
After making my list 1 and list 2, I press stat, calc, then option 1 for vars stats, it doesn’t give me the option to compute both list. When I try entering list 2 with the 2nd button it gives me an error. Can you help me with this?
very nice explanation
0 sense
I am a visual learner....and this helped so much! Thank!
No wonder my profesor doesn’t let me use a T-81 🥲
You lost me at why I need to state my statement
Loved this vid❤
wtf this is so easy when you explain it
what if the sample was smaller than 30? what would happen
then you would need to look at sampling distribution to see if it was aproximatly normal
I think you made a mistake when describing and comparing the Spread
2 mins! I understood better than other videos
How to draw the box in the middle? Ps: thanks this was helpful
Thank you God bless you 😊😊😊😊
I’m sorry but I don’t see any values greater than 32? I don’t see any value that’s even at 32, where do you get those numbers from???
What calculator is this please
where has he been?
Can i get the Z Chart ???
Thanks
your calculator...🔥
