Homework Answers
In experiment design, a residual is defined as the difference between the observed and expected values.
Note: The difference between the observed value of the dependent variable (y) and the predicted value (ŷ) is called the residual (e)

In the design of an experiment we have a treatment τ with four levels η,T2,T3,T4-we are planning to use CRD model and we have only n 20 observations available. How should we allocate the n observations to the four treatments to minimize the average variance of the estimated treatment effects Hint: Find the values of ri by minimizing AV subject to the constraint 4T.
