If we use the tables, then we need to find the z-score. But by inspection we can see it is –3, as was noted above. P(Z < -3) = 0.0013. Thus, the probability of choosing a bag at random, and having the bag weigh less than 5lbs is 0.13%. b. [4] What is the probability that 3 randomly chosen sack of potatoes weigh between 6 and 7 pounds? ................
