Newborn males have weights with a mean of 3272.8 g and a standard deviation of 660.2 g. newborn females have weights with a mean of 3037.1 g and a standard deviation of 706.3 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?

The correct option is:   a female who weighs 1500 g

Explanation

Formula for finding the z-score is:  

Newborn males have weights with a mean of 3272.8 g and a standard deviation of 660.2 g.

So, the z-score for the newborn male who weighs 1500 g will be.......

According to the normal distribution table,  

Now, newborn females have weights with a mean of 3037.1 g and a standard deviation of 706.3 g.

So, the z-score for the newborn female who weighs 1500 g will be.......

According to the normal distribution table,  

As we can see that the probability that a newborn female has weight of 1500 g is greater than newborn male,  so a newborn female has the weight of 1500 g that is more extreme relative to the group from which he came.
