Jiayang's answer to Chowder's Junior College 1 H1 Maths question.
How do u get the -1.0364
I used the calc. There’s an inverse normal dist. function.
You can use the table also but since theres no 0.85 in the table you'll have to do a lil bit of interpolation. Even then your answer won't be as exact as the one obtained from the calc.

How did you get 0.1977?
I take 0.8 from the left column and 0.05 on the top column and they intersect at that point?
