Answer:
please mark brilliant answer
Step-by-step explanation:
Class interval is regular so you have change the class interval into class boundaries
class interval frequency
9.5-19.5. 11
19.5-29.5. 25
29.5-39.5. 16
39.5-49.5. 7
49.5-59.5. 3
largest value=59.5
lowest value=9.5
coefficient of range = l-s/l+s ×100
= 59.5-9.5/59.5+9.5 ×100
=72.46

Answer:
72.46
Step-by-step explanation:
class interval frequency
9.5-19.5 11
19.5-29.5 25
29.5-39.5 16
39.5-49.5 7
49.5-59.5 3
largest value =59.5
smallest value=9.5
= L-S/L+S×100
=59.5-9.5/59.5+9.5×100
=50/69×100
=0.7246×100
=72.46
