Problem #6 [20 28.2 (Est. time 10 min] The volume of fluid that can be poured into a small pitcher follows a Normal distribution with a mean of 1.5 ounces and a standard deviation of 0.3 ounces. The volume of fluid that a large pitcher holds also follows a Normal distribution with mean 2.5 ounces and a standard deviation of 0.4 ounces. A chemistry student pours the fluid in both pitchers. a) How much more fluid would he expect to pour in the large pitcher compared to the small pitcher? b) What is the standard deviation of the difference between the volume of fluid poured in the large and small pitchers? c) What is the probability that the small pitcher contains more fluid than the large pitcher? d) What is the mean and the standard deviation of the total volume of the fluid in two pitchers? e) What is the probability that the total volume of the fluid poured in two pitchers is more than 4.5 ounces
