Question
A research conducts a one-tailed two-sample t test on 32 subjects (16 subjects in each group) and finds that t = 2.182. About what is the actual Type 1 error for the study?
between 2.5 and 3
between 0 and .05
between 3 and 3.5
between 1 and 2.5
A research conducts a one-tailed two-sample t test on 32 subjects (16 subjects in each group) and finds that t = 2.182. How confident can the researcher be that the results are true and not due to mere sampling error?
Around 98%
Around 86%

A research conducts a one-tailed two-sample t test on 32 subjects (16 subjects in each group) and finds that t = 2.182. Report the results as they would appear in an academic journal.
t(30) = .05, p = .83
t(30) = .05, p = .02
t(30) = 2.182, p = .02
t(30) = 2.182, p = .83
