Answer:
Brainliest for no. 7 please
Step-by-step explanation:
no.7
modal is the common age = 12years, because of 21 people, which is the highest no
median is the age at the middle = 13.5y, ( working)
arrange in ascending order, 11, 12, (13, 14,) 15, 16
13 and 14 are in the middle, 13+14÷2= 13.5 years
mean= total÷no
11×10=110 {multiply all the no.}
110+252+104+70+45+48= 629 is the total
no. = 50members
629÷50= 12.58 years
age range= largest-smallest age
16-11=5years
