Unbelievable facts 1: M&M's
Created | Updated Jan 28, 2002
M&M's are peanuts surrounded by something which looks like painted chocolate. They appear in 5 different colours: red, brown, green, blue and yellow. They're sold in pack's of different sizes: 45g, 200g or 400g.
If you've understood my explanations about M&M's, it's time for the REAL problem: how heavy is an M&M's? How many yellow ones are there (proportionnally)?

Statistics
PROCEEDINGS
For the 'work-out', I divided the total of every pack by its mass (I assume, quite wrongly I'm afraid, that the mass given on the pack is perfectly true): The result is a list of numbers which can be compared, because they represent the proportional quantity of M&M's, and not the absolute quantity. Of course, for the mean weight of one M&M's, it's enough to divide the total mass (2835g) by the number of M&M's I've eaten these last 4 months (1304): you'll get 2,174g/M&M's, but you won't get the variance, and other useful things...
If you have a scientific calculator (like mine) (you don't need a big one...), select the mode 'STATISTICS' and insert the list like that:
enter 45 times the totals of the 45g-packs divided by 45 and 200 times the totals of the 200g-packs divided by 200; on my Casio, this would be:
0,43 [ = 86/200] | x | 200 | M+ |
(........)
0,4444444 [ = 20/45] | x | 45 | M+ |
(........)
