Answer:
(5.4582 ; 6.8618) 
Step-by-step explanation:
Given the data:
6 10 2 6 3 3 3 6 6 6 6 5 8 9 10 10 7 9 3 6 5 10 9 9 10 3 8 6 6 3 3 6 6 5 4 10 9 3 5 7 10 6 3 8 6 8 3 3 5 5
Sample mean, xbar = Σx / n
n = sample size = 50
ΣX = 308
xbar = 308 / 50 = 6.16
Using a Calculator :
The sample standard deviation, s = 2.469
Confidence interval = xbar ± margin of error 
Margin of Error = Tcritical * s/sqrt(n) 
Tcritical at 95% ; df = 50 - 1 = 49 
Tcritical = 2.010
Hence, 
Margin of Error= 2.010 * (2.469/sqrt(50)) = 0.7018
Lower boundary : (6.16 - 0.7018) = 5.4582
Upper boundary : (6.16 + 0.7018) = 6.8618
(5.4582 ; 6.8618) 
 
        
             
        
        
        
What do you mean... $245???
        
                    
             
        
        
        
9 - 6 + 4 - 8/3 .., 
geometric series a(n) = a1r^(n-1) 
r = a(n+1)/a(n) 
-6/9 = -2/3 
4/-6 = -2/3 
-8/3/4 = -2/3 
so r = -2/3 and a1 = 9 
Sn = a1(1-r^n)/(1-r) = 9(1-(-2/3)^n)/(1-(-2/3)) 
n is infinite Sn = 9/(5/3) = 27/5 
        
             
        
        
        
-6,-5,0,5,6 that is the order from least to greatest
