Solution

21.

First, we get the z score from the given left tailed area. As          
          
Left tailed area =    0.85      
          
Then, using table or technology,          
          
z =    1.036433389      
          
As x = u + z * s,          
          
where          
          
u = mean =    469      
z = the critical z score =    1.036433389      
s = standard deviation =    119      
          
Then          
          
x = critical value =    592.3355733 -->

Rounding up, 593 [ANSWER, OPTION A]

As

z = (x - u)/sigma

Then

z = (785-591)/148 = 1.310810811 = 1.31 [ANSWER, OPTION C]
