Answer:
False
Step-by-step explanation:
Let p1 be the population proportion for the first population
and p2 be the population proportion for the second population
Then 
 p1  = p2
 p1  = p2 
 p1 ≠ p2
 p1 ≠ p2 
Test statistic can be found usin the equation:
 where
 where 
- p1 is the sample population proportion for the first population
- p2 is the sample population proportion for the second population
- p is the pool proportion of p1 and p2
- n1 is the sample size of the first population
- n2 is the sample size of the second population. 
As |p1-p2| gets smaller, the value of the <em>test statistic</em> gets smaller. Thus the probability of its being extreme gets smaller. This means its p-value gets higher. 
As the<em> p-value</em> gets higher, the null hypothesis is less likely be rejected.
 
        
             
        
        
        
The answer is B.
If he earns $x in one week, then you need 2x to calcualte 2 weeks, add that with his allowance and there you have it.
        
                    
             
        
        
        
8z-8=6z+8
8x-6z=8+8
2z=16
Z=8
        
                    
             
        
        
        
You distribute the negative in the second equation
