Answer 1

Answer:

mean =4.96

s.d q =12.5

C.V = - ×100

25.6= 1.2. / 25.6 ×100

-. =. 1.2 /25.6 × 100

=. 4.96

Answer 2

Answer:

Mean of the data = 8  

Step-by-step explanation:

Given data

(Coefficient of variance) C.V  of a data  = 50%

(Standard deviation)         S.D of a data = 4  

here we need to find mean of the data  

We know that the formula for C.V of a data is given by

                                                 C.V =  $\frac{S.D}{Mean} (100)$  

     from given data    $50 = \frac{4}{Mean} (100)$  

                                      $1 = \frac{4}{Mean} (2)$  

                                     Mean = 8
