Question

Report the t-critical value for a two-tailed test with an α = 0.05 critical threshold and 1 degree of freedom. Report a positive figure without signs. Do not round.

Answer 1

Solution :

Given that,

Degrees of freedom = df = 1

$\alpha$ = 0.05

$\alpha$/2 =0.05/ 2= 0.025

t$\alpha$/2,df = t_{0.025,1 =}

t_{$\alpha$ /2,df} = 12.706
