Hi my question is:

Find the critical value(s) for the t-test with the indicated sample size n and level ofsignificance a.

Right–tailed test,n = 8,a =0.01

Two-tailed test,n = 12,a=0.05

In Excel, using

=T.INV(0.99, 8 - 1)

tcrit = 2.99795 [ANSWER, NUMBER 1]

*************************

In Excel, using

=T.INV(0.025, 12 - 1)

and

=T.INV(0.975, 12 - 1)

tcrit = -2.20098516, +2.20098516 [ANSWER, NUMBER 2]
