Exploring measurements in the Food Industry
Today in chemistry class we were asked the question, Do we get what you pay for? So in the lab we used Hot Cheetos to measure if we do get what we pay for. So we checked our Hot Cheetos bags and it said it contained 28.3g. We used accuracy and precision to measure our bags. Accuracy was measured in the net weight + or - .1g (either 28.2g or 28.4g). Precision was measured as having a variance of less than or equal to .2 grams. We started by measuring the net weight of the bags of Cheetos. The bags measured bag 1 30.8g, bag 2 30.4, bag 3 29.8, and bag 4 30.6g. Later we took out the chips out of the bags and measured them again bag 1 1.5g, bag 2 1.5g. bag 3 1.5, and bag 4 1.5. Then we got the difference for each bag. The precision we got was .9g. So our answer to this project was, No we don't get what we pay for because the accuracy we got wasn't close to 28.2 to 28.4 we got a range of 28.9 and our precision was .9g instead of .
