Answer with Step-by-step explanation:
We are given that n and m are two integers
We have to prove that if n-m is even , then is also even.
We know that sum of two odd numbers is even.Sum of an odd number and even number is odd.
Product of an odd number and even number is even.
Case 1.Suppose m and n are both even n=4 , m=2
Case 2.Suppose m odd and n odd
n=9,m=5
Hence, proved.
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.
