Answer 1

Answer:

2.82 litres.

Step-by-step explanation:

(Refer to attachment).

Here,

Sigma (xi fi) = 25.5 + 32.5 + 35 + 31.5 + 16.5 = 141.

Sigma( fi) = Total number of customers = 50. (already given in question).

Equation to find mean:

Mean = [ Sigma(xi fi) ÷ Sigma( fi) ]

Substituting the values, we get,

Mean = 141/50 = 2.82.

Therefore,

Mean of the milk sold is 2.82 litres.

Points to note: Do not forget to write the unit (here, litres) in the final answer.
