The question is not clearly
So what is the question?
Answer:
Step-by-step explanation:
we know that
The area of a triangle is equal to
------> equation A
where
b is the base of the triangle
h is the height of the triangle
In this problem the dimensions of the triangle are increased by a scale factor of
so
the new dimensions of the triangle are
The new area of the triangle will be
------> equation B
Substitute equation A in equation B
To solve this problem, we have to make use of the standard
probability distribution tables for z test.
Since we are asked to find for the 72 percent level
confidence, then this means we are to look for the value of z which gives
(100-72)/2 = 14% on both sides of the tail.
So at 14% tail on one side, the z value is approximately:
1.08
