Question

Find the mean of first five whole number?
(a)0
(b)4
(c)3
(d)2
(e)none of these​

Answer 1

Answer:

⇒ First 5 whole numbers are 0,1,2,3,4

⇒ sum of the observations (∑x

i

)=0+1+2+3+4=10

⇒ Number of observations (n)=5

⇒ Mean(

x

)=

n

∑x

i

=

5

10

=2

Answer 2

(a) 0- As the first five whole numbers are 0, 1, 2, 3, and 4. Mean = (Sum of observations)/(Number of observations) = (0 + 1+ 2 + 3 +4)/5 = 2.

(b) 4- As the first five whole numbers are 0, 1, 2, 3, and 4. Mean = (Sum of observations)/(Number of observations) = (0 + 1+ 2 + 3 +4)/5 = 2. 4.

(c) 3- As the first five whole numbers are 0, 1, 2, 3, and 4. Mean = (Sum of observations)/(Number of observations) = (0 + 1+ 2 + 3 +4)/5 = 2.

(d) 2- As the first five whole numbers are 0, 1, 2, 3, and 4. Mean = (Sum of observations)/(Number of observations) = (0 + 1+ 2 + 3 +4)/5 = 2.

(e) None of these- As the first five whole numbers are 0, 1, 2, 3, and 4. Mean = (Sum of observations)/(Number of observations) = (0 + 1+ 2 + 3 +4)/5 = 2.
