Think about doing a One-Sample t-test.Think about doing step two, looking up the t-critical.Which option below contains only things that are correctly matched for looking up a t-critical?

Group of answer choices

One tail, predicted decrease, = .05, n = 60, t-critical = -1.671

One tail, predicted increase, = .01, n = 60, t-critical = +2.423

Two tails, = .01, n = 20, t-critical = 2.539

Two tails, = .05, n = 30, t-critical = 2.042
