Newborn Elephant Weights Newborn elephant calves usually weigh between 200 and 250 poundsuntil October 2006

, when an Asian elephant at the Houston (Texas) Zoo gave birth to a male calf weighing in at a whopping 371

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 225 pounds with a standard deviation of 45 pounds, what is the probability of a newborn weighing at least 371 pounds? Assume that weights of newborn elephants are normally distributed. Use a TI-83 Plus/TI-84 Plus calculator and round the answer to at least four decimal places.
