Question

Find the area that corresponds to each of the following z-score values.

1. z = 2.86

2.  = -0.91

3. z = -1.6

4. z = 1.32

5. z = -2.18

Answer 1

he area that corresponds to the z-score value is probability that standard normal distribution variable will be less than z-score value

1 $P(Z<2.86)=0.99788$

2 $P(Z<-0.91)=0.18141$

3 $P(Z<-1.6)=0.05480$

4 $P(Z<1.32)=0.90658$

5 $P(Z<-2.18)=0.01463$
