Use the five step process to determine each of the following areas 1. Between z = 0 and z = 2.67 2. Between z = -0.78 and z = -1.95 3. Between 1.27 and z = -2.1 4. To the right of z = 0.33 5. to the Left z = 1.96

1.

$P(0<Z<2.67)=P(Z<2.67)-P(Z\le 0)$

$\approx0.9962074-0.5\approx0.496207$

2.

$P(-1.95<Z<-0.78)$

$=P(Z<-0.78)-P(Z\le -1.95)$

$\approx0.2176954-0.0255881\approx0.192107$

3.

$P(-2.1<Z<1.27)$

$=P(Z<1.27)-P(Z\le -2.1)$

$\approx0.8979577-0.0178644\approx0.880093$

4.

$P(Z>0.33)=1-P(Z\le0.33)$

$\approx0.370700$

5.

$P(Z<1.96)\approx0.975002$
