ANSWER:
A. y= -4x - 4
EXPLANATION:
y2-y1
——— This is used to find the slope
x2-x1
4-(-4)=8
0-2=-2
8/-2=-4
So the slope should be -4.
Since the y-intercept is shown in (0,4), the y-intercept is 4.

Answer:

The confidence level is 0.98 and the significance is
and
and the critical value using the table is:

And replacing we got:

Step-by-step explanation:
For this case we have the following info given:
represent the population deviation
the sample size
represent the sample mean
We want to find the margin of error for the confidence interval for the population mean and we know that is given by:

The confidence level is 0.98 and the significance is
and
and the critical value using the table is:

And replacing we got:

Cut 25 with 5
5x3 = 15
15 = 15
