The next time you make a trip to a supermarket, ask the manager if you can measure the mass of at least 10 cereal boxes of your choice. Choose the same brand and the same size boxes. Tell the manager this is an assignment for a class. Report the average mass, variance, and standard deviation for the cereal boxes. Does the manufacturer’s information noted on the box fall within your measurement?
Repeat Problem using three other products, such as cans of soup, tuna, or peanuts.
