From the scatter plot below
we know that Y=Cost of electricity (estimated value)
X= Total number of machine hours of machine Time
for each of the 52 weeks
The relationship between Y and X are given in the regression equation
Using the above equation, the estimated cost of electricity when the total machine hours are zero (X=0) is
that is even when the machines are not run, the cost of electricity is estimated to be $263.4. This is the fixed cost of running.
The fixed cost is estimated to be $263.4
Next we look at the coefficient of determination, indicated
by value. From the
graph we know that
This indicates that 54.3% (which is 0.543*100) of the variation in the cost of electricity is explained by the change in total number of machine hours of machine time.
ans: The fixed cost estimate is $263.4, and the coefficient of determination suggests that 54.3% of the change in the cost of electricity is explained by the change in total number of machine hours of machine time.
