A researcher conducts a study on a new antidepressant and finds a p-value of 0.03.
Which statement accurately describes the statistical interpretation of this finding if the significance level (α) is set at 0.05?
- The study demonstrates high clinical significance no matter how small the observed effect size is.
- The null hypothesis is accepted here simply because the calculated p-value obtained is greater than zero.
- The null hypothesis is rejected; there is a 3% probability of obtaining these results if the drug has no effect.
- There is a 97% probability that this particular antidepressant drug is truly effective in the general adult population.
