an educational researcher is analyzing the test scores for statistics students taught using two different methods: a traditional method and a web-based self-paced method. randomly selected students from both groups were given the same test; the data is shown below: traditional web-based self-paced sample size: 80 40 mean test score: 84 81 population variance: 28 40 this data is then used (along with a .05 significance level) to test the claim that the mean test score for the web-based self-paced method is lower than that of the traditional method. what is the p-value for the test?
