(m) Mean marks obtained by the group.​

Answer 1

Answer:

(i) highest marks obtained by students = 95

lowest marks obtained by students = 39

(II) range = highest value - lowest value =95-39=56

(iii) mean = sum of all observation / total no. of observation = 85.76+90.85+39+48+56+95+81+75/8 =570.61/8=71.326
