I hope it workssssssssssssssssssssss.
Line AB contains points A(-6,3) and B(2,-5). Line AB has a slope that is?

So 1st, divide the shape into multiple other shapes.
BTW, sorry if I take long I'm trying to draw the lines on the picture.
Then, the area of a triangle in a=bh(1/2) and for trapezoids, it's (1/2(length of base 1+ length of base 2))height, so, do that for the 2 trapeziods, and do that for the triangles. I got 42.

You are asked:
a) the estimate
b) the standard error
c) the multiplier
A) The point estimate is given by:
p = sample size / population size
= 44/80
= 0.55
B) The standard error is given by:
SE =
=
= 0.0556
C) In order to find the multiplier (z-score), you first need to calculate the probability:
(1-0.80)/2 = 0.10
Now, look at a z-table to find z = 2.32
