Answer:
There is not enough evidence to support the claim that Alaska had a lower proportion of identity theft than 23%.  
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 1432
p = 23% = 0.23
Alpha, α = 0.05
Number of theft complaints , x = 321
First, we design the null and the alternate hypothesis  
 
This is a one-tailed test.  
Formula:
 
 
Putting the values, we get,
 
Now, we calculate the p-value from the table.
P-value = 0.298
Since the p-value is greater than the significance level, we fail to reject the null hypothesis and accept the null hypothesis.
Conclusion:
Thus, there is not enough evidence to support the claim that Alaska had a lower proportion of identity theft than 23%.
 
        
             
        
        
        
Answer:
$276
Step-by-step explanation:
Create a proportion where x is the cost to refinish the larger wood floor:
 =
 = 
Cross multiply and solve for x:
3x = 828
x = 276
So, to refinish the larger wood floor, it would cost $276
 
        
             
        
        
        
$200 x 0.00295
= $0.59
The price of the toy car in 1968 was $0.59
        
                    
             
        
        
        
The modal score would be 71. 71 appears the most in the list.
