Answer:
 
  
Now we can calculate the p value. Since is a bilateral test the p value would be:  

Since the p value is lower than the significance level of 0.05 we have enough evidence to conclude that the true proportion of residents favored annexation is higher than 0.72 or 72%
Step-by-step explanation:
Information given
n=900 represent the random sample selected
 estimated proportion of residents favored annexation
 estimated proportion of residents favored annexation
 is the value that we want to test
 is the value that we want to test
 represent the significance level
z would represent the statistic
 represent the p value
 represent the p value 
Hypothesis to test
The political strategist wants to test the claim that the percentage of residents who favor annexation is above 72%.:  
Null hypothesis: 
  
Alternative hypothesis: 
  
The statistic for this case is given by:
 (1)
 (1)  
Replacing the data given we got:
 
  
Now we can calculate the p value. Since is a bilateral test the p value would be:  

Since the p value is lower than the significance level of 0.05 we have enough evidence to conclude that the true proportion of residents favored annexation is higher than 0.72 or 72%
 
        
             
        
        
        
5+7+11=23
3+11+53=67
3+11+61=71

Slope of the equation is -9/2
Step-by-step explanation:
- Step 1: Write the equation in slope-intercept form y = mx + b
9x + 2y = 9
2y = -9x + 9
y = -9/2 x + 9/2
⇒ Slope, m = -9/2
