Answer:
Degree of freedom is 6.
Step-by-step explanation:
A sample of seven infants is randomly selected and their weights at birth are recorded.
Given, Population mean = 6.6 pounds
Sample size = n = 7
Degree of freedom = n - 1
= 7 - 1
= 6
Degree of freedom is 6.

<h3>What is monomial factorization ?</h3>
A monomial is an expression that is the product of constant and non-negative integer powers of x, like
..
A monomial is expressed as a product of two or more other monomials when it is factored.
Here,
a = 125

To find: a - b
a - b = 125 - 
a - b = 
We know that,

Finding the factored form of a - b using this method:


So, factored form of a - b is
