To find the mean, we need to add up all the scores and divide by the total number of students:
(60+60+65+65+70+70+70+70+70+70+70+70+75+75+75+75+75+75+80+80+80+80+80+80+85+85+85+90+90+90+90)/38
Simplifying this expression gives us:
2330/38 = 61.32
Rounding to the nearest tenth, the mean score is 61.3.
(60+60+65+65+70+70+70+70+70+70+70+70+75+75+75+75+75+75+80+80+80+80+80+80+85+85+85+90+90+90+90)/38

2330/38 = 61.32
Rounding to the nearest tenth, the mean score is 61.3.
