I know this isn't really computer-technical. But I got to solve this with my brains and my calculator (TI-84 Plus), which both are computers so please help me... (fast? )
I got math exam on monday and I'm totally stuck with this exercice...
I calculated the Z-score for both the 230 and 425 (with the InvNorm command of the calculator) but well I'm sort off stuck now...
The solution should be 359 according to the book, but I need to found out how you calculate it...
+rep for everyone who helps ofc...
Thx in advance
Edit: Problem solved thx anyway

What is the average of the entree exam...
