A sample of n = 25 scores produces a t statistic of t = -2.062. If the researcher is using a two-tailed test, which of the following is the correct statistical decision? Group of answer choices: A. The researcher can reject the null hypothesis with alpha = .05 but not with alpha = .01. B. The researcher must fail to reject the null hypothesis with either alpha = .05 or alpha = .01. C. It is impossible to make a decision about H0 without more information. D. The researcher can reject the null hypothesis with either alpha = .05 or alpha = .01.

05 and α = 0.01. Since the sample size is n = 25, the degrees of freedom (df) will be n - 1 = 24. For α = 0.05, the critical t-value for a two-tailed test is t(0.025, 24) (since each tail has 0.025 significance level). Using a t-distribution table or calculator, Show more…

A single sample t-test conducted on a sample of n = 20 participants produces a t statistic of t = 2.53. For a two-tailed test, what is the correct decision about the outcome of the test? A. The researcher can reject the null hypothesis with α = .05 but not with α = .01. B. The researcher can reject the null hypothesis with α = .01 but not with α = .05. C. The researcher must fail to reject the null hypothesis with either α = .05 or α = .01. D. The researcher can reject the null hypothesis with either α = .05 or α = .01.

A researcher obtains t = -2.25 for a repeated-measures study using a sample of n = 10 participants. Based on this t value, what is the correct decision for a two-tailed test? Group of answer choices a.) fail to reject the null hypothesis with both α = .05 and α = .01 b.) reject the null hypothesis with α = .05 but not with α = .01 c.) reject the null hypothesis with both α = .05 and α = .01 d.) fail to reject the null hypothesis with α = .05 but not with α = .01
