Assume thаt vоlumes оf bоttles of root beer аre normаlly distributed with a mean of 20 fluid ounces and a standard deviation of 0.3 fluid ounces. a.   Find the probability that a bottle of root beer has more than 21 fluid ounces.  Do not round your answer. b.  Find the probability that a group of 16 bottles of root beer has a mean volume that is less than 19.8 fluid ounces.  Do not round your answer. c.  In part b, we can assume that the mean volumes have a normal distribution even though our sample size was less than 30.  According to the Central Limit Theorem, why can we make this assumption? d.  The root beer company plans to discount the price of root beer bottles with the lowest 2% of volumes.  Find the volume of a bottle of root beer that separates the lowest 2% from the rest.  Do not round your answer.
