Chris Graham commented on Perform an independent two sample t-test 1 year, 3 months ago

Part b) asks for the test statistic, which is used as part of the adaptive marking in part a), so part (a) ends up pending with the "This feedback is based on your last submitted answer. Submit your changed answer to get updated feedback" message after submitting part b). It caused some confusion when students moved between questions in the exam, as they were presented with the warning that not all questions were submitted.
