To determine the average weight of carry-on luggage by passengers in airplanes, a sample of 52 pieces of carry-on luggage was weighed. The average weight was 26 pounds. Assume that we know the standard deviation of the population
to be 6 pounds.
Determine a 97% confidence interval estimate for the mean weight of the carry-on luggage. Provide the lower limit of the
confidence interval.

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
