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  243 pounds with a standard deviation of 46  pounds, what is the probability of a newborn weighing at least 384 pounds? Assume that weights of newborn elephants are normally distributed. Round  z -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
