A study based on a sample of 17 participants calculates a value of 2.33 for the t-test for a single mean. For alpha (α) = .05 (two-tailed), which of the following is the correct way to present this analysis? A) t(16) = 2.33, p .05 C) t(17) = 2.33, p .01

Question

A study based on a sample of 17 participants calculates a value of 2.33 for the t-test for a single mean. For alpha (α) = .05 (two-tailed), which of the following is the correct way to present this analysis? A) t(16) = 2.33, p < .05 B) t(16) = 2.33, p > .05 C) t(17) = 2.33, p < .05 D) t(17) = 2.33, p > .01

The correct way to present the t-test analysis is with degrees of freedom (df), which is calculated as the sample size minus one (n-1). For a sample of 17, df = 17 - 1 = 16. The notation "t(16) = 2.33" correctly reflects this. The p-value is determined by comparing the calculated t-value against a t-distribution table or using statistical software. If the statement indicates "p < .05," it means the result is statistically significant at the alpha level of .05, assuming a two-tailed test was used.
