Birth weights of babies born to full-term pregnancies follow roughly a normal distribution. at meadowbrook hospital, the mean weight of babies born to full-term pregnancies is 7 lbs with a standard deviation of 14 oz (1 lb = 16 oz). dr. watts (who works at meadowbrook hospital) has one delivery (for a full-term pregnancy) coming up tonight. what is the probability that the baby will weigh more than 7.5 lbs?
