Answer:
Step-by-step explanation:
100-115 is a modal class.
L=100
f1 - frequency of class modal class =11
f0- frequency of class preceding to modal class =9
f2- frequency of succeeding to modal class =8
Mode =L+[f1-f0/2 x f1 - f2-f0] xh
=100+[11-9/2x11-9-8]x15
=100+2/22-9-8]x15
=100+2/5x15
=100+2x3......dividing 15 by 5
=100+6
=106
Thus, the modal bowling speed is 106km/h.
