Answer :
- The mean of teachers ages are 37.30.
Step-by-step explanation:
Given that
- Ages of teachers:
29, 38, 39, 26, 29, 29, 39, 77, 38, 29
To find
- The Mean of teachers ages ?
So, according to the question
We have,
- Ages of teachers:
- 29, 38, 39, 26, 29, 29, 39, 77, 38, 29
So, we know that
- The mean of any given data
mean = [tex]\frac{sum\;of\;\;data}{number\;of\;data}[/tex]
- So, the sum of the teachers ages
∑ Ta = 29+ 38+ 39+ 26+ 29+ 29+ 39+ 77+ 38+ 29
∑ Ta = 373
- The number of teachers
Tn = 10
Now, The Mean of teachers ages
Tm = [tex]\frac{sum\;of\;the\;teachers\;ages}{number\;of\;teachers}[/tex]
Tm = [tex]\frac{T_a}{T_n}[/tex]
= [tex]\frac{373}{10}[/tex]
Tm = 37.30
Answer:
- The mean of teachers ages are 37.30.
