Answer:

1. range = highest observation- lowest observation

=54-23

=31

2. total sum of age / no. of teachers

=(42+28+32+41+33+54+27+23+34+37)÷10

= 35.1

Answer 2

arranging the data in ascending order

23,26,28,32,33,35,40,41,54.

age of the oldest teacher = 54

age of the youngest teacher = 23

1. Range = Age of old teacher - age of young teacher

54 - 23

= 31

2. mean age = sum of all Teacher upon/ number of teachers

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

= 350/10

= 35 ans.
