Question 973238: a bottle shop sell o average 2500 bottles per day with standard deviation of 300 bottles assuming that the number is normally distributed, calculate the percentage of days when between 2200 and 2800 bottles are sold Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website!
z= (x-mean)/standard deviation
(2200-2500)/300= -1
(2800-2500) = 1
z between -1 and +1 is 68.32%
This is part of the empiric rule.
