Helpfull

Thanks ma'am this video was very helpful 😊

Thank you so much. This was extremely helpful😊

Wow I have my test in 30 minutes time and this video is very helpful…I love you ma’am !

Thank you sooo soo much I just could not get it. But now I saw it immediately with your amazing explanation. 🙏

What is the difference between a Menu 6,6,3 and Menu 6,7,3. one is confidence interval, and the other is a Stat test, but I dont know what that means.

Awesome

if only our teacher explained it like this, thank you! i finally understand

This is honestly so HELPFUL!!!

How do you find the class boundaries?

Ripoff khan academy 😂

Thanks a lot for this detailed explanation.

You are a life saver, I knew my calculator would be used, thank you so much

Great help

What about division?

Thank you so much for this video

Thank you so much you really help me with my school works❤❤

Thank you so much!

made it soo simple an ezyy i swearr

brilliant and simple

Thanks it works 😁

My teacher could not explain it but it took u less than 10 mins to explain

That was very helpful.thank you so much

Why are you 13

When I did the tally’s for my chart the numbers were too large for the classes ?

There is another way of doing this with the n nspire cx2 that looks the same, but with hitting menu,6,3 then selecting sample or pop. I dont understand really whyh it coulld not be added into the calculation. When doing Var, and Std it seems like will likely be calculated at the same time and displayed with the mean.

what if the question doesnt have any data set but asks for variance and deviation for samples of the following (n=8, Ex^2=87,Ex=26)

I have a question: what if we are given a circle and it's not stated that there's a centre and also we r not given any radius . How do i work it out wen asked to write the equation of a circle

I had no idea you could insert 'Z' value into the NORM.DIST function. That's clever, thank you.

thanks

I have come across a book that provided an amazing shortcut for these questions. It suggested that we imagine creating a square with the given perimeter (2500 yd). Therefore, the side length of the square would be 625. Subsequently, we just need to calculate the area of this square, which is straightforwardly obtained by squaring 625, yielding the identical solution of 390625.

Thankyou, easy and simple.

Cleared up 2 hours of confusion!!

Thanks for this. I was doing this by hand because I don't know how to use stat crunch yet.

A n B pls

Do for A n B

Thank you 😀 And God bless you

this was really helpful!

Thank you very much for your explanations, they are very clear and they managed to made me understand how quartiles works. Thanks from France

Very clear and concise video, you explained the entire concept so beautifully, without wasting any time ❤ thank you so much ❤❤

Yes I have a question about give example of empty or null set and define it

Thanks for the information

I can be wrong here but you made a slight error. For One-tailed test, you reject H0 when p<alpha and reject if p=>alpha(not 100% sure but I checked multiple sources). For two-tailed test, you reject H0 at 2*p<alpha.

Thank you 🙏🙏🙏

Please continue posting!!

Thanks Ma'am, Respect from India 🌺♥️

Great video! I have one question, for the problem F, what can you do in excel if it is 2<X<5 rather than 2=<X=<5? Thanks!

Is this Ms. Sara

you're goated 🙏 had no idea how to save my equations on my calculator and im taking ap precalc test tomorrow
