On average fisherman catch 10,000 fishes a month with standard
deviation of 1,500. If fishermen around the world was asked to
present their weekly averages. Find the probability that (assume
variable is normally distributed):
Central Limit theorem
100 fishermen catch more than 10,500 fish a week
100 fishermen catch less than 10,100 fish a week
100 fishermen catch between 9,000 and 11,000 fish a week
