Answer 1

Step-by-step explanation:

Firstly Arrange these Observations in increasing Order,

5 5 5 6 6 6 6 7 7 7 7 7 8 8 9 9 9 10 10 10

Mean = Sum of all Observations / Number of all Observations

= 5+5+5+6+6+6+6+7+7+7+7+7+8+8+9+9+9+10+10+10 / 20

= 147 / 20

= 7.35

Firstly all Number of Observations is in Even i.e., 20

Median = (n/2 +1)th terms and (n/2)th terms (Here, n = 20)

= (20/2 +1)th and (20/2)

= 11th terms and 10 th terms

i.e., 7 and 7

Mode = Highest Number of Frequency in Observation

= 7

Because, 7 has highest Frequency in this Observation.
