Solution

Using technology, we get                  
                  
slope =    1.649315068              
intercept =    3.243835616              
                  
Thus, the regression line is                  
                  
y^ = 3.24 +    1.65 x   [ANSWER]

******************************
                  
Thus, if x =    5.5              
                  
Then                  
                  
y^ =    12.315 = 12.32 [ANSWER]
