Find table in the back of your statistics text labeled something like "areas under normal distribution" to find the proportion related to that Z score. In this case, you are looking for the "area in the larger portion."
but i cant find the proportion for a z-score of 1.98
on the table thingy... do i use 1.90 and 2??
My "table thingy" has Z scores to two decimal places. If you have a 1.90 value, there should also be a 1.98 value. Use that.
soo ive got the porpotion. Do i have to do anything with that or is that my answer???
