Answer:   <em>r</em> represents a significant linear correlation.
Step-by-step explanation:
GIven : Linear correlation coefficient: r = 0.543
Sample size: n= 25
Significance levle: 
Degree of freedom : n-2 = 25-2=23
Now, we check <em>r</em> critical value table for value with df = 23 and  .
.
 Critical value = ±0.396  [From <em>r</em> critical value table]
 
Since r = 0.543 > 0.396, that means there is significant linear correlation.
Hence,  <em>r</em> represents a significant linear correlation.
 
        
             
        
        
        
171 rounds to 200, and 727 rounds to 700. 700+200= 900.
The answer is 900.
        
                    
             
        
        
        
24. 
This is because if we double the base and the height in the area equation it will raise any number by a factor of 4.
