Answer #1

1. The area under the normal curve between the mean and a score for which z=1.75 is

Here, we have to find P(0<Z<1.75) = P(Z<1.75) – P(Z<0)

P(0<Z<1.75) = P(Z<1.75) – P(Z<0)

P(0<Z<1.75) = 0.959941 - 0.5

(by using z-table)

P(0<Z<1.75) = 0.459941

Answer: 0.4599

2. In a normal distribution, the fraction of scores that lie between z= -.40 and 1.20 is

P(-0.40<Z<1.20) = P(Z<1.20) – P(Z<-0.40)

P(-0.40<Z<1.20) = 0.88493 - 0.344578

(by using z-table)

P(-0.40<Z<1.20) = 0.540352

Answer: 0.5403
