What does the standard normal curve graph look like with the shaded area that is to be found:$0\mathrm{.}24)=0\mathrm{.}4052$

Using excel NORMSDIST $(1\mathrm{.}20)=0\mathrm{.}8849$

Explanation:

We determine probability.

Answer

a$)$ To the left of z $=-2$ or to the right of z $=2,$ it is $0\mathrm{.}0456$

b$)$ To the left of z $=-1\mathrm{.}56$ or to the right of z $=2\mathrm{.}56$ is $0\mathrm{.}0646$

c$)$ To the left of z $=-0\mathrm{.}24$ or to the right of z $=1\mathrm{.}20$ is $0\mathrm{.}5203$
