The mean weight for a newborn baby is 7.5 pounds. The standard deviation is 1.2 pounds. Newborn weights, like many bio-metrics, follow a normal distribution. What is the probability of randomly selecting a newborn whose weight is greaterthan 8.7 pounds? (hint: use the empirical rule) What is the probability of randomly selecting a newborn whose weight is below 5.5 pounds? Would you consider it unusual for a newborn to weigh less than 5 pounds? Whyor why not? What is the probability that a random sample of 9 babies have a mean weightgreater than 8.7 pounds?
