The correct option is: a female who weighs 1500 g
<em><u>Explanation</u></em>
<u>Formula for finding the z-score</u> 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 <u>probability that a newborn female has weight of 1500 g is greater than newborn male</u>, so a newborn female has the weight of 1500 g that is more extreme relative to the group from which he came.
Answer:
There is one solution
Step-by-step explanation:
2x + y = -1
8x + 3y = -2
Multiply the first equation by -4
-8x -4y = 4
Then add the equations together to eliminate x
-8x -4y = 4
8x + 3y = -2
--------------------
-y = 2
Multiply by -1
y =-2
Now find x
2x+y =-1
2x+-2 =-1
Add 2 to each side
2x-2+2=-1+2
2x=1
Divide by 2
x = 1/2
