Find the indicated probability using the standard normal distribution: P(z<-1.45)

Answer 1

Find table in the back of your statistics text labeled something like "areas under normal distribution" to find the proportion/probability related to the Z score.

Answer 2

Do I have to subtract that number from 1? That's really the part I can't remember...there's some time when you leave it alone and another when you subtract from 1...?

Answer 3

Look up the Z score on that table. You are looking for probability of Z score less than (<) -1.45.
