P()----> Area less than z value R()----> Area greater than z value Q()----> Area between 0 and z value

[@MagicalDanny]

If anyone is wondering how to do something like P(-2.8 < Z < 1.4) = 0.9167 the step for that is shift stat/dist, distribution, p, then do P(1.4) then do the same for P(-2.8) The final answer is whatever value you get for P(1.4) subtracted by P(-2.8) which should end up being approximately 0.9167

...And when I saw the table in the stats lecture I thought, yeah right there has got to be a better way, all that messy interpolation. My exams are 8 weeks away and I will become a Jedi Master in this...Presentation wise you are absolutely spot on. I don't know why the heck the tables are needed. Am I going to do the Exam on the same island Tom Hanks was stuck on in Castaway, yeah throw in the abacus while you're at it. lol!

[@mikebabz9755]

No you don't need an abacus, Just come with your table and chair 🤗

[@97MrOmar]

Thank you man you're work is sick and is helping me a lot

[@tri-hun-fri]

Thank you! There are almost no videos on using this calculator. Your awesome!

[@ExamSolutions_Maths]

Thank you for watching and any support you show for this project.

[@hassan010012]

Thanks! I'd like to ask a question, please! How we use the calculator to calculate the z-score if the probability is given?

[@calavino223]

[@saikikusuo7361]

Thanks for this sir.

[@dorsmovies]

Got a question, Is there a way to do the function Qnorm in the program R, which shows you percentages before a value? For example Qnorm(0.1) is -1.281 because 10% of the area under the graph is before -1.281. This is the opposite of p(-1.281) that will give me 0.1.

[@sathyasuthahar5207]

[@darklord2909]

Any idea how to enter this question. “ on investigating The labour efficiency an organisation is found that there is typically a favourable mean of $65000 and a standard deviation of $5000. What is the probability that the variance is less than $45000?”

[@philipshergold4771]

Does the Casio fx-85GT PLUS have the 'Distribution' calculation type?

Hi did you ever find the distributing function? £25 seems a lot to get a new calculator because mine is missing one function

[@macronelmacron7133]

How can I find Z when I already have the probability????????

[@random-accessmemory9201]

Macron Elmacron you compute it using calculus.

[@akashanil4540]

z = (x - μ) / σ

[@vocassen]

You'd want the invert function of this, which the calculator does not support, so you'd be back to using tables

[@AbdullahiIdri2001]

Why not just use the Normal C.D function and use the values of the SND? It gives identical answers and I'm assuming I wouldn't lose marks as all the working out is done via calculator anyway.
