Consider the following sample of data.

Y 11.8 21.1 26.8 32.4 33.6
X 2.7 3.9 3.8 5.6 5.7

For this data, we have that:

  • SXX=  
  • SYY=
  • SXY=
  • β^0=
  • β^1=
  • The test statistic for the test that β1=0 is:

Solutions

Expert Solution

Sxx = 6.612

Syy = 321.312

Sxy = 43.412

Beta 0 = -3. 3549

Beta 1 = 6.5656

Test statistics = beta 1 / Se(Beta 1) = 6.5656/1.35 = 4.85
