Answer:
Yes! 
The solution to the equation is n = 2
Step-by-step explanation:
Given the equation

remove the parentheses

Add 3 to both sides

Simplify

Add 2n to both sides

Simplify

Divide both sides by 6

Simplify

Therefore, the value of n = 2.
Hence, 
Yes! 
The solution to the equation is n = 2
 
        
             
        
        
        
<u>Answer:</u>
<u>Null hypothesis: Policy B remains more effective than policy A.</u>
<u>Alternate hypothesis: Policy A is more effective than policy B.</u>
<u>Step-by-step explanation:</u>
Remember, a hypothesis is a  usually tentative (temporary until tested) assumption about two variables– independent and the dependent variable.
We have two types of hypothesis errors:
1. A type I error occurs when the null hypothesis (H0) is wrongly rejected.
 That is, rejecting the assumption that policy B remains more effective than policy A when it is <em>actually true.</em>
2. A type II error occurs when the null hypothesis H0, is not rejected when it is actually false. That is, accepting the assumption that policy B remains more effective than policy A when it is <em>actually false.</em>
