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.

Z for males = 2.57

Z for females = 2.06

male value is more extreme

Step-by-step explanation:

Z score represents how many standard deviation you are from the mean.

The formula is:

Z = (Value - Mean)/(ST. DEV.)

For newborn males:

Z = (1500-3292.4)/697.5 = 2.57

For newborn females:

Z = (1500-3000.6)/727.9 = 2.06

Z score for newborn males is bigger, therefore 1500 is more extreme relative to the group

points are handed out whenever you post answers.

brainliest answers are handed out by the person asking the question, so whether your answer is picked depends entirely on whether the asker bothers to pick

if you're asking about your rank, it depends on having a certain number of points and a certain number of brainliest answers. for example, at the time of this writing, i have 44338 points out of 15000 needed for the next (nearly triple the requirement! ) but i only have 24 out of 50 required brainliest answers. this number decays, meaning after a certain amount of time (i think about a month), the total number of brainliest answers you've earned doesn't count toward this total. (i've been stuck at the same rank for a long

the lesson to learn here is that you shouldn't worry about points or rank. chances are, no matter how good an answer you may provide, your efforts will go mostly unnoticed unless you focus on the newest/most active questions that get posted.
