Estimate, ok
area=side^2
if we round
25^2=625 
25.3 is slighly bigger so maybe 632 squaer centimters or something
        
             
        
        
        
Answer:

Step-by-step explanation:
<u><em>the mean in period</em></u> 1 :
(2.3+2.1+2.2+2.2+2.2+2.1+2.4+2.5+2.2+2.0+1.9+1.9+2.1+2.2+2.3)÷15=21.733...
<u><em>the mean in period</em></u> 2 :
(2.3+2.1+3.3+1.5+3.6+1.6+3.0+1.1+4.7+2.1+2.4+1.9+2.8+0.5+2.3)÷15=23.466...
Since 23.466 > 21.733 then “The mean in period 2 is higher than the mean in period 1”.
 
        
             
        
        
        
The proportion of businesses who did not respond = 54.67%
Given : Total businesses = 150
Businesses responded = 68
Businesses did not respond =  150- 68 = 82
The proportion of businesses who did not respond =
82/150 x 100
54.67%
