Yes they are
When a research question asks you to find a statistical sample mean (or average), you need to report a margin of error, or MOE, for the sample mean. The general formula for the margin of error for the sample mean is the population standard deviation, n is the sample size, and z* is the appropriate z*<span>-value for your desired level of confidence

Answer:
3600 pounds
Step-by-step explanation:
One cubic foot of a chemical weighs 60 pounds.
1 ft³ of chemical = 60 pounds
We need to find how many pounds in the container whose dimension 6 ft, 4 ft and 2.5 ft
l = 6 ft
b = 4 ft
h = 2.5 ft
Volume of box = lbh
= 6 x 4 x 2.5
= 60 ft³
As we are given
1 ft³ of chemical = 60 pounds
60 ft³ of chemical = 60 x 60 = 3600 pounds
