Obtain the estimate regression equation.
Examine the coefficient of determination and the adjusted of
determination. Does it seem that either of the independent
variables’ addition to R2 does not justify the reduction
in degrees of freedom that results from its addition to the
regression model? Support your assertions.

Each column represents a different treatment given to sick rats.
Each cell is a different rat. Use statistical analysis and use post
hoc testing using contrasts to find the best
treatment.
Treatment 1: vitamins
Treatment 2: prescription pills
Treatment 3: brain surgery
Treatment 4: shock therapy
Treatment 5: dietary changes
