to simplify expressions for the test statistics.)
3. Carry out the test of the hypotheses in Question 2 using the set of data in Question 1.
Use α = 0.05.
1 4. Let where the εi’s are independent and identically distributed as N(0, σ2). It is desired to
test H0: β1 = 0, β2 = β3 against H1: β1 ≠ 0 and/or β2 ≠ β3. The observed values of yi’s
are given as follows: y1 = 3.2, y2 = –3.4, y3 = 0.8 and y4 = –1.2.
(iv) State the full and reduced mo...
