Use z scores to compare the given values.
based on sample data, newborn males have weights with a mean of 3292.4 g and a standard deviation of 697.5 g. newborn females have weights with a mean of 3000.6 g and a standard deviation of 727.9 g. who has the weight that is more extreme relative to the group from which they came: a male who weighs 1500 g or a female who weighs 1500 g?
since the z score for the male is z
equals
=
and the z score for the female is z
equals
=
, the
female or male
has the weight that is more extreme.
