Answer:
The 95 percent confidence interval for the population mean is between 14.736 tons and 16.864 tons.
Step-by-step explanation:
We have the population's standard deviation, so we can find the normal confidence interval.
We have that to find our
level, that is the subtraction of 1 by the confidence interval divided by 2. So:

Now, we have to find z in the Ztable as such z has a pvalue of
.
So it is z with a pvalue of
, so 
Now, find the margin of error M as such

In which
is the standard deviation of the population and n is the size of the sample.

The lower end of the interval is the sample mean subtracted by M. So it is 15.8 - 1.064 = 14.736 tons
The upper end of the interval is the sample mean added to M. So it is 15.8 + 1.064 = 16.864 tons
The 95 percent confidence interval for the population mean is between 14.736 tons and 16.864 tons.
Answer:
15 feet = Length
Step-by-step explanation:
The area of a rectangle is:
Area = Length x Width
The Area is given as 180 square feet (ft2) and the width is given as 12 feet. Let's plug those values into the Area formula to find the length:
Area = Length x Width
180 = Length x 12
Divide both sides of the equation by 12:
180/12 = Length
15 feet = Length
