Question

You are trying to determine the statistical significance of an equation. Given the following information, test the slope of the equation at the 95% level of confidence. Select the correct answer out of each pair of choices.

Cost = 521.44 – 53.50 (Resolution)    n=10   Sb1 = 5.645

   The tp is 2.306
   The tp is 1.860

   The tc is (-) 9.477
   The tc is (-) 92.372

   We would reject the null hypothesis
   We would fail to reject the null hypothesis

   We would consider using the equation
   We would not use the equation

Explanation / Answer

The tp is 2.306
