value. Because you have symmetry on both sides, for example if the critical value with an area to the right of 4% and 10 degrees of freedom you could find invT(0.04,10) and you would get -1.948. Since you actually wanted the area to the RIGHT to be 0.04 and this found the area to the left, just use positive 1.948 and that is the answer.

Anne finds the regression coefficient significant at the 3% level, and adopts the 1% significance level - she does not reject the claim that the multiplier equals one. Ben (another economist), analyzing the same data but adopting the 5% significance level, would draw the opposite conclusion: the multiplier is significantly different from one.

is set to 1.358 (1.224) when the test is performed at the 5% (10%) significance level. The KS test may be regarded as a distribution-free test because its null distribution does not depends upon the explicit form of the distribution under analysis. In other words, the critical values obtained from equation 2 are
