Newborn Elephant Weights Newborn elephant calves usually weigh between 200 and 250 pounds-until October 2006, when an Asian elephant at the Houston (Texas) Zoo gave birth to a male calf weighing in at a whopping 384 pounds! Mack (like the truck) is believed to be the heaviest elephant calf ever born at a facility accredited by the Association of Zoos and Aquariums. If, indeed, the mean weight for newborn elephant calves is 244 pounds with a standard deviation of 50 pounds, what is the probability of a newborn weighing at least 384 pounds? Assume that weights of newborn elephants are normally distributed. Round 2-value calculations to 2 decimal places and final answer to at least 4 decimal places. The probability that a newborn elephant weighs at least 384 pounds is
