b. State the linear model for this problem. Define all notation andmodel terms.
c. Create the design matrix for this problem.
d. Estimate model parameters for this problem using ? =(?T?)-1?T?
e. Interpret the meaning of the estimates from part d.
f. Rerun this problem using lm()in R. Interpret the coefficients inthe output.
g. Rewrite the model in as a linear regression using dummyvariables. Confirm the
results from part f. agree with the results from part g.
h. Perform a one-way ANOVA of Bread using a randomization test onthe
SandwichAnts dataset.
