Table A 6 lists critical values of r for selected values
Table A-6 lists critical values of r for selected values of n and a. More generally, critical r values can be found by using the formula
Where the t value is found from the table of critical t values assuming a two tailed case with n – 2 degrees of freedom. Use the formula for r given here and Table A-3 to find the critical r values corresponding to H1: p ≠ 0, α = 0.02, and n = 27.
