Question 918974: The volumes of soda in quart bottles are normally distributed with a mean of 32.0 oz and a standard deviation of .19 oz. How many BOTTLES from a case of 48 will have LESS THAN 31.8oz?
Is this right?
32.0-31.08/.19/SR48?

mean of 32.0 oz and a standard deviation of .19 oz
n = 48

x-bar come first
z(31.8) = (31.8 - 32)/(.19/sqrt(48) = -.2/ .0274 ~ -7.3
P(z < -7.3) basically zero
1 at the very most... will have LESS THAN 31.8oz
None would be more likely
