5. Weights of babies at the local community hospital have a distribution that is approximately normal with a mean weight of 7.43 pounds and a standard deviation of 1.25 pounds. A premature baby can be classified as being less than 5.51 pounds. Answer the following questions:

a. Find the probability of a randomly selected baby weighing less than 5.51 pounds.  mean: 7.43 stdev: 1.25 x: 5.51 Probability 0.06226919

b. If 25 babies are randomly selected, what is the probability that their weight will be less than 5.51 pounds?  (I'm having difficulty understanding part b).
