Question

please give me correct information​

Answer 1

Answer:

(i) age of the oldest teacher = 54

age of the youngest teacher = 23

(ii) age of the oldest teacher - age of the youngest teacher = 54 - 23 = 31

range of ages = 31

(iii) mean = sum of the observation / no: of observations

= ( 32 + 41 + 28 + 54 + 35 + 26 + 23 + 33 + 38 + 40 )/10

= 350/10

= 35

therefore mean = 35

i think this is the answer...........I hope this helps u
