The researcher who assisted with the workshop (and with other workshops) decided to test if there was a difference in knowledge and performance between educators in the "humanities" program (English andFrench program areas) and those in the "sciences" program (Biology and Physics program areas). Was there a difference on the initial test mark means between these two groups in the workshop? Was there a difference in composite performance indicator score means between these two groups? (Conduct statistical tests to determine if the differences are significant. State hypotheses, critical values for thet-statistic, and decision rules for the statistical tests, and make sure to make meaningful concluding statements.)

I don't understand what they're looking for.
