Question 4 1 pts It is known that the birth weights of newborn infants carried to "full term" (pregnancies lasting between 37 and 42 weeks) have an approximately normal distribution with a mean of 7.3 pounds and a standard deviation of 1.3 pounds. A local hospital delivers 40 babies per week. Treating each pregnancy as a random sample, and assuming the patients in this hospital have babies that follow the distribution above, what is the probability that the average birth weight of 40 babies in a week will exceed 7.7 pounds
