Question

The following results were reported for an independent samples t test: t(18) = +2.15, p < .05. The results suggest that
A) H₀ should be rejected.
B) H₀ should fail to be rejected.
C) the results are unlikely if H₀ is true.
D) both "a" and "c" above.

Quizplus · Accepted Answer

The t-test result of t(18) = +2.15 with a p-value less than .05 suggests that the observed data are unlikely under the null hypothesis (H₀), indicating statistically significant differences between the groups. Therefore, H₀ should be rejected (A), and the results are unlikely if H₀ is true (C), making both A and C correct.
