Use z scores to compare the given values.   Based on sample​ data, newborn males have weights with a mean of 3286.4 g and a standard deviation of 875.2 g. Newborn females have weights with a mean of 3072.8 g and a standard deviation of 588.9 g. Who has the weight that is more extreme relative to the group from which they​ came: a male who weighs 1600 g or a female who weighs 1600 ​g?
