Check my working

Apparently in CAS they penalise calculator syntax. I'm not sure though, seeing as I did non-CAS, like you..

I can't imagine them honestly wanting though..

This could be right; sorry guys, i'm not sure on this. Yet what m@tty is saying makes sense, as if they'd expect that kinda working out when its not formally taught. Its like asking you to work with integrals using a sigma instead of the integral sign...

My class was taught that actually :/ I never write it though, and my teacher hasn't told me anything about not using it. But at the same time, he didn't exactly tell us about avoiding calculator syntax either

Pretty sure it's always like 2 marks for the question.

So saying Pr(Z<z)=whatever is one mark then z=whatever is the answer mark.

But you could do it to be safe I guess.

I was taught it last year, just as an aside though.

What Martoman was saying was it isn't formally taught because it isn't in the study design.

I think you can communicate those like Pr(Z<x-u/o)=... (as suggested by Martoman)
Using inversenorm, z=... therefore u=....
Writing the whole function is a bit excessive
