Correct Answer Question No. 13 • calculate skewness when mean= 24.75, mode=30 and standard deviation=9.16 Answer​

Answer 1

Answer:

hey here is your solution

pls mark it as brainliest

Step-by-step explanation:

$to \: find : \\ pearsonian \: coefficient \: of \: skewness \\ (Skp) \\ \\ given : \\ mean \: (x) = 24.75 \\ \\ mode = 30 \\ \\ SD \: (σ) = 9.16$

$so \: we \: know \: that \\ \\ Skp = \frac{mean - mode}{S.D} \\ \\ = \frac{24.75 - 30}{9.16} \\ \\ = \frac{ - 5.25}{9.16} \\ \\ = - 0.5731441 \\ \\Skp ≈ - 0.57$

$so \: as \: here \\ Skp < 0 \\ \\ the \: distribution \: of \: data \: is \: \\ asymmetrical \: negatively \: skewed \: \\ \\ therefore \: then \\ \\ mode > median > mean$
