21. Birth weights of babies born to full-term pregnancies follow roughly a normal distribution. At Asian Hospital, the mean weight of babies is 7 Ibs with a standard deviation of 14oz. (1 lb = 14 oz). Dr. Watts has four deliveries coming up during the night. Assume the birth weights of these babies can be viewed as a simple random sample. 16. What is the probability that the average weight of the four babies will be more than 7.5 lbs? 0.65% 15.87% 12.65% 30.85% 22. When one is using the standard normal distribution, P(z < 0) = can not be determined 1 O 0.5
