You want to create a 99% confidence interval for a word problem. For your 99% C.I., you need a t-critical to plug in to your C.I. formula. You can borrow the t-critical from your friend—who already did that same word problem as a hypothesis test—but ONLY if your friend’s hypothesis test was _______________. Group of answer choices α = .05, two tails α = .01, two tails α = .01, one tail (predicted decrease) α = .05, one tail (predicted increase) α = .01, one tail (predicted decrease) α = .05, one tail (predicted increase)
