Tell me plz about inverse normal distribution on casio fx99ies plus calculator
Inverse fi
thank you that was really helpful ❤️
is there a calculator which has the chi-square function but which is non-programmable? because in the exam I am not allowed to have a programmable calculator.
maybe you could just use the formula and then the table of values and values of freedom in the exam? idk
When do you use binomial pd and binomial cd on the calculator ?
pd when you want to find the P(X=x) and cd when you want to find P(a
thanks
You are one stupendously helpful chap!
@Baylor Marcos I dont think I will
Does the inverse normal distribution always have to be less than
The *7* option is not there in my Casio fx-991ARX classwiz calculator :(
Neither
How can we do this using f(x) 991ES plus calculator
Nope, You cant use the inverse Distribution.
But, If your asking how to use the calculator to find a normal distribution then:
1) Click on mode and then press 3
2)the during the options click Ac
3)Hold shift and choose 1
4)Select 5
Had me exam in this y'day! :(
Can you upload your economics notes please
I hope it went well for you
ExamSolutions when do you use binomial pd and bionomial cd on this calculator?

can you pls tell which casio classwiz calcullator it is fx991ex or what?
And also can i do inverse normal disturbution on casio fx 991es

Hello sir i know you highlighted my comment but if you can pls paste the link of your video if you created any over here.
wait so you don't need to multiply the deviation with 6? you can just use zero instead?
Sorry, I would like to help but I am confused by your question.
in 9:55, you did mention that for the lower bounds we should remember to multiply the deviation with 6 and then subtract with the mean, but then you used zero instead.
I now understand your question. Yes I said take a value at least 6 standard deviations below the mean. That would be 50 - 6(0.2) = 48.8. I know 0 is way below this but would still be fine. Just saved me working out 48.8 and entering a value. Try 47, 46 ... etc and you will see you will get the same answer as I did.
@@ExamSolutions_Maths thank you! i was also wondering if you could help me out with a few pure maths p3 questions, i have my exam tmrw
I wish I could but I get tons of questions from people each day asking much the same thing. Best wishes though for your exam.
Is this as level content or a level ?
A-Level under the new spec
ExamSolutions thanks
For question c, isnt the probability for p(m
I can see your confusion. Although the questions a, b and c all use m, they are different values of m for each question. It does say find the mass m of a sweet when .....
at 7:20, can you not answer it using 0.3 instead on 0.7? I don't understand why its necessary to to answer it the same way as part a even when its a different question
The calculator is only capable of giving the observed value in the inverse normal function if you provide the probability of being less than a value. NOT more than as indicated in the red box at the top of the video.
