A researcher is interested in determining whether course delivery mode (online v on-ground) has had an effect on students' final exam scores. Below are the scores for each group. Conduct a two-samples t-test to determine if there is a significant difference between average scores in both groups. Assume alpha =0.05 Copy/paste the data below into an Excel Sheet (or Google Sheets) and run a two-samples t-test. Copy/paste the results into the response window below. Be sure to include your interpretation of the results. In your answer, state the null and the research hypotheses and explain whether the results of the two-sample test led you to reject or fail to reject the null hypothesis.
