thank you that was really helpful ❤️

[@abunchofiguanaswithinterne2186]

You are one stupendously helpful chap!

[@abunchofiguanaswithinterne2186]

@Baylor Marcos I dont think I will

[@unknownzzz9089]

Does the inverse normal distribution always have to be less than

[@Ijustwantsomemilk]

For question c, isnt the probability for p(m

[@ExamSolutions_Maths]

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 .....

Tell me plz about inverse normal distribution on casio fx99ies plus calculator

[@manalhashmi5803]

Inverse fi

[@SupremeVEX]

When do you use binomial pd and binomial cd on the calculator ?

[@ExamSolutions_Maths]

pd when you want to find the P(X=x) and cd when you want to find P(a

[@SupremeVEX]

thanks

[@roseytb4092]

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.

[@GrannyGr]

maybe you could just use the formula and then the table of values and values of freedom in the exam? idk

[@HasnainAli-pw4se]

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

[@HasnainAli-pw4se]

How i do inverse normal disturbution on casio fx 991es

[@HasnainAli-pw4se]

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.

[@adammorsel]

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

[@ExamSolutions_Maths]

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.

[@toyahan7195]

The *7* option is not there in my Casio fx-991ARX classwiz calculator :(

[@Test-ri2kr]

Neither

[@faizasaeed9691]

How can we do this using f(x) 991ES plus calculator

[@thelaststanding6634]

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

[@SupremeVEX]

Is this as level content or a level ?

[@ExamSolutions_Maths]

A-Level under the new spec

[@SupremeVEX]

ExamSolutions thanks

[@lifewithdylan]

Had me exam in this y'day! :(

[@SupremeVEX]

Can you upload your economics notes please

[@ExamSolutions_Maths]

I hope it went well for you

[@SupremeVEX]

ExamSolutions when do you use binomial pd and bionomial cd on this calculator?

[@dhruvkhanna1215]

wait so you don't need to multiply the deviation with 6? you can just use zero instead?

[@ExamSolutions_Maths]

Sorry, I would like to help but I am confused by your question.

[@dhruvkhanna1215]

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.

[@ExamSolutions_Maths]

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.

[@dhruvkhanna1215]

@@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

[@ExamSolutions_Maths]

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.
