The following sample observations were randomly selected Rou

The following sample observations were randomly selected (Round your answers to 2 decimal places.) a. The regression equation is Y = b. When X is 7 this gives Y =

Solution

Using technology, we get              
              
slope =    0.363013699          
intercept =    3.767123288          
              
Thus, the regression line is              
              
y^ =    3.767123288 + 0.363013699 x [ANSWER]

Thus, if x =    7          
              
Then              
              
y^ =    6.308219178   [ANSWER]
