Answer:
A. We have extremely strong evidence to reject H0.
Step-by-step explanation:
Let P be the proportion of non-retirees in 2015 who did not think that Social Security would be able to pay a retirement benefit by the time that they retire.
According to the data null and alternative hypotheses should be:
 : P=0.60 : P=0.60
 : P<0.60 : P<0.60
Test statistics is -4.29 and p-value of the statistics is p<0.001
At every significance levels higher than 0.001, we can reject the null hypothesis since p<0.001. 
 
        
             
        
        
        
3.95 × 3.81 = 15.0485
The road was 15.0485 miles long after the renovation.
