The total energy need during pregnancy is normally distributed, with mean of 2600 kcal/day and a standard deviation of 50 kcal/day. What is the probability that a randomly selected pregnant woman has an energy need of more than 2625 kcal/day? Is this result unusual? [Recall unusual means the probability is less than 5%, Make Sure you answer BOTH parts]
