Answer :
SOLUTION:
We want to draw graphs showing the following:
A, All values to the right of z = 2.86
This is the plot, the area is marked in red;
The numerical value for this area is;
[tex]P\left(z>2.86\right)=0.0021182[/tex]B. All values Not between -1.09 and 0.16 standard deviations from the mean.
The numerical value for this area which is the sum of the blue and red areas is;
[tex]P\left(z<-1.09\text{ }or\text{ }z>0.16\right)=0.5743[/tex]
