Answer:
The margin of error will be "0.65". A further explanation is provided below.
Step-by-step explanation:
The given values are:
n = 343
x = 110
At 99% confidence level,
%
then,
or,
Now,
The point estimate will be:
⇒
⇒
⇒
or,
⇒
⇒
The margin of error will be:
⇒
On substituting the above values, we get
⇒
⇒
⇒
hence,
⇒
⇒
⇒
You would first calculate the price per pound and then use that to calculate the correct price of each bag.
To solve for the value of x, you can simply add all of the values and expressions together and make it equal to 180 degrees, since the sum of all angles in a triangle add up to this amount.
Then we can solve for X, by algebra.
