Answer :
A
Solution :
Given observation are
5,5,5,5,5.
∴ x¯=5+5+5+5+55=255=5
Now, σ2=∑i=15(xi−x¯)2N
Where N = total number of observations.
∴ Variance=σ2
(5−5)+(5−5)+(5−5)+(5−5)+(5−5)5=0
Hence, standard deviation =var−−−√=0

Answer:
The variance of the given series is 0.
Step-by-step explanation:
We know that ² =
where ² = Variance
= 'i'th term of the series
= mean of the series
N = number of terms in the series
Here, =
=
= 5
= (5 - 5) + (5 - 5) + (5 - 5) + (5 - 5) + (5 -5)
= 0
Therefore, ² =
= 0
Therefore, the variance of the given series is 0.
