THE NEXT QUESTIONS ARE BASED ON THE FOLLOWING INFORMATION: A sample of 10 observations produces the following summary values: ?(xi - x?)? = 10815.472, ?(xi - x?)Ā³ = 72.48 and SĀ² = 28.044 What is the approximate value of skewness? A. 1.375 B. 0.221 C. 0.049 D. 1.173

Step 1
We are given the sum of the observations, $\sum x_i = 10815.472$, and the sum of the squared observations, $\sum x_i^2 = 72.48$. We also know that the sample variance is $S^2 = 28.044$. Show moreā¦
