State the total degrees of freedom for following 1 Critical

State the total degrees of freedom for following:

1.) Critical value 1.645 for one tailed test, alpha = .05

2.) Critical value = 63.657 for a two tailed test, alpha = .01

Solution

1) using a T-dist table you can find the degrees of freedom = 1000
2) using a T-dist table you can find the degrees of freedom =1
