A(n) was performed to assess whether mean HR differed significantly for a group of 10 participants who consumed no caffeine (Group 1) compared with a group of 10 participants who consumed 150 mg of caffeine (Group 2). The result was statistically significant, t (18) = -2.75, p = .013, two-tailed, 95% CI [-17.81, -2.39]. Mean HR for the no caffeine group (M = 57.80, SD = 7.20) was about 10 bpm lower than mean HR for the caffeine group (M= 67.90, SD = 9.10). Which type of test is this? O Paired samples t-test MANOVA O Independent samples t-tes ANQYA
