3. Let Bo and ₁ denote the least squares estimators of Bo and 3₁. Define SSE = Σ(Yi-Bo- i=1 B₁X₁)². Show that (a) E (SSE) = 0², (b) cov(Y, ₁X) = 0. 4. In Section 10.4, we defined a test statistic where s² = T = VSEZ SSE. In addition, it is known that T~: n-2' (a) Show that (1) can be re-written as 1 tn-2. T = r√n-2 (1) (2) (b) Use Part (a) to test Ho: p = 0 vs H₁ p 0. [Hint: (2) can be regarded as a test statistic under Ho.]

in as nd PROBLEM 6.7-12 6.7-13 A cantilever beam with a rectangular cross seeon (width b = 20 mm, height h = 175 mm) is loaded by a force P that acts at the mid-height of the beam and is inclined at an angle a to the vertical (see figure). Two strain gages are placed at point C, which also is at the mid-height of the beam. Gage A mea- sures the strain in the horizontal direction, and gage B measures the strain at an angle ß = 60° to the hor- izontal. The measured strains are &₁ = 145 × 10-6 and & = -165 × 10-6.
