utorial Exercise Consider babies born In the "normal" range of 37-43 weeks gestational age. A paper suggests that a normal distribution with mean u = 3,500 grams and standard deviation o = 400 grams reasonable model for the probability distribution of the continuous numerical variable x = birth weight of a randomly selected full-term baby. (a) What is the probability that the birth weight of a randomly selected full-term baby exceeds 4,000 g? (b) What is the probability that the birth weight of a randomly selected full-term baby is between 3,000 and 4,000 g? (c) What is the probability that the birth weight of a randomly selected full-term baby is either less than 2,000 g or greater than 5,000 g
