Answer 2

Answer:

Mean = 30.75

Step-by-step explanation:

MARKS :                      0-10  10-20  20-30  30-40  40-50  50-60

NO. OF STUDENTS :   10      18        27         32      24        09

mid points:                     5        15       25        35       45        55

$X_{i} F_{i}$                                50      270     675     1120     1080    495

∑$x_{i} f_{i}$ =  3690

total no of student = 120

N = $\frac{120}{2}$ = 60

Mean =3690/ 120 = 30.75
