Q1) In particular region of Cape Cod, it is known that lobstermen trap on average of 32 pounds of lobster per day with standard deviation of four pounds. If random sample of 30 lobster fishermen is chosen, determine the probability that their average catch is less than 31.5 pounds?

Q2) Mean weight of loads of coal placed in train cars by loading machine is 43.0 tons with standard deviation of 8.0 tons.
