Beerball Posted July 21, 2012 Posted July 21, 2012 how much does it weigh? There's no way that all those bags weigh 10 pounds or 5 ect. How much leeway is given when they package produce?
DC Tom Posted July 21, 2012 Posted July 21, 2012 If you buy a 10 pound sack of potatoes, it weighs 10 pounds. If it doesn't weigh 10 pounds, you didn't buy a 10 pound sack. Frickin' duh.
millbank Posted July 21, 2012 Posted July 21, 2012 potato weighing machine Ten pound bags of potatoes do not weigh ten pounds, but are produced by a machine that attempts to produce a ten pound average weight. In an effort to see if the machine is properly set up, the foreman at the potato bagging plant weighs 16 bags of potatoes produced by the machine. Here are the results: 10.07 10.35 10.05 9.98 10.27 10.46 9.95 10.44 10.08 9.90 10.10 10.18 10.39 9.96 10.19 10.47 From past experience it is known that the machine produces bags whose weights are approximately normally distributed and have a standard deviation of around 1/4 of a pound.

The Poojer Posted July 21, 2012 Posted July 21, 2012 I'm gonna throw the bull stojan flag...unless we have gotten less tech savvy since I was in college but weights and measures is highly monitored. I worked at a Pepsi bottling plant and even the slightest bit under the 16 oz(for cans) got rejected and got taken home by workers every 2 weeks....10# is 10#... Just because the bag says 10 pounds doesn't mean it's 10 pounds Thanks!
DC Tom Posted July 21, 2012 Posted July 21, 2012 Just because the bag says 10 pounds doesn't mean it's 10 pounds But you didn't ask "How much does a sack of potatoes weigh if it says ten pounds?" You asked "How much does a 10 pounds sack of potatoes weigh?" It weighs 10 pounds. Don't blame me...I gave you the right answer, you just asked the wrong !@#$ing question.
Beerball Posted July 21, 2012 Author Posted July 21, 2012 I'm gonna throw the bull stojan flag...unless we have gotten less tech savvy since I was in college but weights and measures is highly monitored. I worked at a Pepsi bottling plant and even the slightest bit under the 16 oz(for cans) got rejected and got taken home by workers every 2 weeks....10# is 10#... Much different though. You know exactly how much goes into a 1 litre bottle. You can't expect that every bag of potatoes, carrots, lettuce is exact weight. Only way you could do it would be to lop off some and then people would B word about the waste. But you didn't ask "How much does a sack of potatoes weigh if it says ten pounds?" You asked "How much does a 10 pounds sack of potatoes weigh?" It weighs 10 pounds. Don't blame me...I gave you the right answer, you just asked the wrong !@#$ing question. JERK I AUGHTA POUR A BEER OVER YOUR HEAD!
Just Jack Posted July 21, 2012 Posted July 21, 2012 My families favorite shopping trick, weighing the 10lbs (or whatever the bag says for the produce you want) to get the heaviest bag. Millbank is correct that their is deviation in the bags as they are filled.
BuffaloBill Posted July 21, 2012 Posted July 21, 2012 You should weigh the bag at home and then return to the store and complain when it does not weigh exactly 10 lbs. this way you will be known as a jerk at your local grocery.
Corp000085 Posted July 21, 2012 Posted July 21, 2012 (edited) Statistically speaking, it has a weight of 10 lbs within a statistical confidence level. In real words, your bag weighs very close to 10 lbs. if you have a million bags of 10 lb potatoes, you can be at least 95% sure that they weigh within one standard deviation of the 10lb mean. http://en.m.wikipedia.org/wiki/Student's_t-test Edited July 21, 2012 by Corp000085

Better yet - return the .2 lbs of overage to them. Hey, they could put that half a potato back on the shelf.
/dev/null Posted July 21, 2012 Posted July 21, 2012 What weighs more? 10lb sack of potatoes? 10lb bag of feathers? 10lb bowling ball?

You want me to do that again? What weighs more? 10lb sack of potatoes? 10lb bag of feathers? 10lb bowling ball? Would have to be the sack of potatoes.
mead107 Posted July 21, 2012 Posted July 21, 2012 Just open 2 bags and take 3 potatoes and put them in the bag you want to buy. Works every time.
ICanSleepWhenI'mDead Posted July 21, 2012 Posted July 21, 2012 . . . if you have a million bags of 10 lb potatoes, you can be at least 95% sure that they weigh within one standard deviation of the 10lb mean. http://en.m.wikipedia.org/wiki/Student's_t-test I'm not sure I've ever seen a 10 lb potato. But if you did have a million bags of 10 lb potatoes, they would weigh at least 10 million lbs, even if you only had one 10 lb potato in each bag. You only missed the correct answer by at least 9,999,990 lbs.

That's how healthcare's gonna work... Some get 10.47, some will get 9.90... If everybody is truthful, it all comes around... You don't keep on picking up 9.9 bags or 10.47 bags. Ut oh... Now I did it... Disregard the above.
/dev/null Posted July 21, 2012 Posted July 21, 2012 Just open 2 bags and take 3 potatoes and put them in the bag you want to buy. Works every time. If you take potatoes out of one 10lb bag and put them into another 10lb bag, you no longer have a 10lb bag of potatoes
ExiledInIllinois Posted July 21, 2012 Posted July 21, 2012 Does it not explain the 10 pound situation on the the bag? Something like "by volume." ??
