Question

You can insert Desmos graphs or hand-drawn graphs.Draw a normal curve representation for the area, then write thenumerical value of the area under the normal curve for each of thefollowingA) All values to the right of z=2.86B) All values Not between -1.09 and 0.16 standard deviations from themean. (hint: if you use Desmos, you will need to create two graphs)Edit View Insert Format Tools Table

Answer 1

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;

`P\left(z>2.86\right)=0.0021182`

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;

`P\left(z<-1.09\text{ }or\text{ }z>0.16\right)=0.5743`
