Assume that cans of Coke are filled so that the actual amounts have a mean of 12.00 oz and a stand. dev. of 0.11 oz
a) Find the P that a sample of 36 cans will have a mean amount of at least 12.19 oz.
b) Based on the result from part a, is it reasonable to believe the cans are actually filled with a mean of 12.00 oz? if the mean is not 12.00oz, are consumers being cheated?
