Answer:
ok mate
Step-by-step explanation:
(i) Arranging the ages in ascending order, we get:
23, 26, 28, 32, 33, 35, 38, 40, 41, 54
We find that the age of the oldest teacher is 54 years and the age of the youngest
teacher is 23 years.
(ii) Range of the ages of the teachers = (54 – 23) years = 31 years
(iii) Mean age of the teachers
=
23 26 28 32 33 35 38 40 41 54
10
=
350/10
10 years = 35 year
