The mean score for a standardized test was 62%. Reviewers considered the score to be too low so the test was revised and the new mean score was 68% with a standard deviation of 2.2% Has the test actually been made significantly easier? (worth 10 marks)
Can anyone explain to me what steps id take to answer this question? Im not asking you to do my homework im just asking for guidance.
Thanks
