A reasearcher computes an inferential statistics to test the difference between mean scores for an experimental and control group. The probability of the obtained statistical value for the t-test is .025which is less than the alpha level of significance (p < .05). The researcher should .

neither accept nor reject the null hypothesis of no difference because the probability value of .025 is significantly different than .05.

reduce the alpha level of significance to .025 to form a definite conclusion.

None of these choices

reject the null hypothesis of no difference between the experimental and control groups because the probability is so small; thus, the independent variable had a reliable effect on the dependent variable.

accept the null hypothesis of no difference between the experimental and control groups because the probability is so small; thus, the independent variable had no effect.
