Cans of regular Coke are labeled as containing 1211 oz 8 can

Cans of regular Coke are labeled as containing 12.11 oz. 8 cans will have a mean amount of at least 0.11 oz. Find the probability that a sample of 12.00 oz and a standard deviation of 12.11. Assume that cans of Coke are filled so that the actual amounts are normally distributed with a mean of 8 randomly chosen cans, and found the mean weight to be 12 oz. Statistics students weighted the content of

Solution

mu =12. sigma = 0.11

x bar = 12.11

n =8

This is comparison of sample means with population mean and getting p value

X>12.11

z > (12.11-12)/0.11/rt 8

Z.>2.83

From std normal distribution table we find

P(Z>2.83) = 0.5-0.4977

=0.0023
