Answer:
Ascending order of data= 35, 36, 38, 39, 40, 42, 44, 45, 46, 49, 53, 55
Step-by-step explanation:
- The age of the eldest teacher in the school is 55 years.
- The age of the youngest teacher in the school is 35 years.
- The range of age of the teacher in the school is (55 - 35)= 20 years
- The mean age of the teachers in the school= Sum of number/Total number
=(35 + 36 + 38 + 39 + 40 + 42 + 44+ 45+ 46+ 49+ 53+ 55)/12
= 522/12
= 43.5 years
