(for your answer enter only one word: positively, negatively or symmetrical.what is the value of the coefficient of skewness using pearson's coefficient of skewness?What is the value of quartile 2?

Answer 1

Answer:Mean = $248

Median = $252

Quartile 3 = $265

Mode = $265

range = $69

Standard deviation= 20.126

Coefficient of variation = 8.115

Negatively

Coefficient of skewness = -0.596

Quartile 2 = $252
