Answer:
The  value is   
 
Step-by-step explanation:
From the question we are told that 
      The null hypothesis is  
      The level of significance is  
From the z table  the critical value of   considering the two tails of the normal  curve( This is because this a two tailed test ) is
 considering the two tails of the normal  curve( This is because this a two tailed test ) is 
        
Hence the critical value is  
         
 
          
 
        
             
        
        
        
97.45 • 0.18 = 17.54. 97.45 + 17.54 = 114.99. I think this is right.

Answer:
- 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 3x + 9 ← is in slope- intercept form
with slope m = - 3
Parallel lines have equal slopes, thus
y = - 3x + 4 ← is the equation of a parallel line
