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?  A. One tail, predicted decrease, a=.05, n=60, t-critical= -1.671 B. Two tails, a=.01, n=20, t-critical=+/- 2.539 C. Two tails, a=.05, n=30, t-critical= +/- 2.042 D. One tail, predicted increase, a=.01, n=60, t-critical +/- 2.423

Describe when you would use an independent samples t-test versus a dependent samplest-test.

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, α = .05, n = 60, t-critical = -1.671 Two tails, α = .01, n = 20, t-critical = ±2.539 One tail, predicted increase, α = .01, n = 60, t-critical = +2.423 Two tails, α = .05, n = 30, t-critical = ±2.042
