Answer 1

Answer:

hey here is your solution

pls mark it as brainliest

Step-by-step explanation:

$to \: find = \\ coefficient \: of \: variation \: \: (C.V) \\ \\ given : \\ S.D (σ) = 5 \\ \\ mean \: (x) = 60 \\ \\ we \: know \: that \\ \\ C.V = \frac{ σ\times 100}{x} \\ \\ = \frac{5 \times 100}{60} \\ \\ = \frac{500}{60} \\ \\ = 8.33333 \\ \\ C.V≈8.33\%$
