The nelson company makes the machines that automatically dispense soft drinks into cups. Many national fast food chains such as mcdonald’s and burger king use these machines. A study by the company shows that the actual volume of soft drink that goes into a 16-ounce cup per fill is normally distributed with a mean of 16 ounces and a standard deviation of 0. 35 ounces. A new 16-ounce cup that is being considered for use actually holds 16. 7 ounces of drink.
