Answer:
Mean of a grouped data is
Sum of F x/ sum of frequency F
Sum of F = 5 + 15 + 13 + 10 + 7 = 50
to find x find the average of the two classes
That's
0 + 10/2 = 10/2 = 5
10+20/2 = 15
20 + 30 / 2 = 25
30+40 /2 = 35
40+ 50 / 2 = 45
Therefore sum of Fx = 5(5) + 15(15) + 13(25) + 10(35) + 7(45)
= 1240
Therefore
Mean = 1240/50
= 24.8cm
I hope this helps you
