Normal approximation of binomial distribution doubt (1 Viewer)

How would you find the value when the inside is negative like in P(z<-1.12)?

How would you find the value when the inside is negative like in P(z<-1.12)?

You would need to use table. The first step would be knowing how the table is defined.

Your question does not have anything to do with binomial distribution.

Yeah I know it has to do with the table but the table doesn't have negative values on it so what would you do?

You utilise the symmetry properties of the normal distribution.
P(Z < -1.12)
= P(Z > 1.12)
= 1 - P(Z < 1.12)
