Question

Can someone help me with determing the area under the standard curve that lies on the right of z = -3.0 =? Thank you

Answer 1

Can you look up z-table?

Answer 2

Yes I can but I thought I'd look under z -3.0 then under the .01 but it's not the same answer as the back of the book. It looks like they went under the 3.0 then under .01 wouldn't it be - since the number is -3.0?

Answer 3

I'm looking for the table, meanwhile post your answer choice up!

Answer 4

I think I found why they look under positive numbers because it says to convert the value to a z - using z = x -

Answer 5

0.9987

Answer 6

you have z = -3 already
