Answer:
The margin of error of the sample mean is 0.648.
Step-by-step explanation:
The standard error(margin of error) of a sample mean is given by the following formula:
In which s is the standard deviation of the sample and n is the size of the sample.
In this problem, we have that:
So
=1.5
Y = mx + b
y = how far up
x = how far along
m = Slope or Gradient (how steep the line is)
b = value of y when x=0
80 ft
Perimeter is adding the lengths of all the sides.
