Determine the critical value of t in the following circumstance: 1alpha=0.99, n=10
t9 = 2.2498
t9 = 3.2498
t9 = 1.2498
t9 = 4.2498

If 1  alpha = 0.99, then alpha = .01
Degrees of freedom is n  1, which would be 9 in this case.
Check a tdistribution table. You should be able to narrow down the value from the data given.
