Unless otherwise stated, carry out inferences using a = 0.05. Hypotheses should be written in terms of parameters when possible, and conclusions of hypothesis tests should be given using the context of the problem. Continue to use the data set from problem 1, after removing the two unrepresentative student records. For notational convenience, define X = test a) Obtain numeric values for the following quantities. i. SSTO ii. SSR(X) iii. SSE (X) iv. SSR (X21XD) SSR (X31X,X2) vi. SSR(X, 1X2, X3) b) Compute the following coefficients of partial determination. i R 211 ii. R3112 R$123 c) Explain what your value of R$3_12 signifies. V. *** . d) Using the following model, Y = Bo + B,X1 + B2X2 + B3X3 + € conduct a partial F-test of whether X, and X, can be dropped from the model simultaneously. Give the hypotheses, test statistic, p-value, and conclusion,
