Two researchers completed the same study when considering the same hypothesis test. Researcher A obtained a p-value of 0.10. Researcher B obtained a p-value of 0.13. Based on this information, the p-value from researcher [answer1] provides stronger evidence against the null and in favor of the alternative.  Using a significance level of 0.05, researcher A should [answer2] the null and researcher B should [answer3] the null.
