i think you need some sort of table for this, but not really we can guess at the answer easy

anonymous · Answer

the mean is 3.25 and the standard deviation is .25 
so 2.75 is two standard deviations below the mean, and the grocer is taking everything from there on up

you have 4 options and only one of them is large, pick that one
