(a)

To determine

To calculate: The skewness coefficient of the production data. The production, population, and consumption of different countries are shown below:

$\begin{array}{cccc}\text{Country}& \text{Population}& \text{Production}& \text{Consumption}\\ \text{China}& \text{1350}& \text{97}\text{.8}& \text{109}\text{.6}\\ \text{US}& \text{317}& \text{78}\text{.0}& \text{97}\text{.5}\\ \text{Russia}& \text{143}& \text{54}\text{.9}& \text{32}\text{.8}\\ \text{Canada}& \text{35}& \text{18}\text{.8}& \text{13}\text{.5}\\ \text{India}& \text{1221}& \text{16}\text{.0}& \text{23}\text{.6}\\ \text{Brazil}& \text{201}& \text{9}\text{.9}& \text{11}\text{.7}\end{array}$

(b)

To determine

To calculate: The skewness coefficient of the consumption data, whose production, population, and consumption of different countries are shown below.

$\begin{array}{cccc}\text{Country}& \text{Population}& \text{Production}& \text{Consumption}\\ \text{China}& \text{1350}& \text{97}\text{.8}& \text{109}\text{.6}\\ \text{US}& \text{317}& \text{78}\text{.0}& \text{97}\text{.5}\\ \text{Russia}& \text{143}& \text{54}\text{.9}& \text{32}\text{.8}\\ \text{Canada}& \text{35}& \text{18}\text{.8}& \text{13}\text{.5}\\ \text{India}& \text{1221}& \text{16}\text{.0}& \text{23}\text{.6}\\ \text{Brazil}& \text{201}& \text{9}\text{.9}& \text{11}\text{.7}\end{array}$
