Administering tests to statistics students

Assignment Help Basic Statistics

Reference no: EM13104514

Over many years of administering tests to my statistics students I have found that the overall average of the scores on the first exam that I give each semester is 76.

Well, this semester my class (36 of them -- assume this is a sample) scored an average score of 80 on the exam (standard deviation was 6). At the .05 level of significance, is this class smarter than the classes I usually have?
