 Type of spam Percent Adult 19 Financial 20 Health 7 Internet 7 Leisure 6 Products 25 Scams 9 Other ?

## Part (a) Step 2: Concept

The distribution of a category variable is displayed using pie charts and bar graphs. Any set of quantities measured in the same units can be compared using bar graphs. It's a good idea to ask yourself, "What do I see?" when looking at any graph.

## Part (a) Step 3: Explanation

The above information is listed in the following table.

Since the total percentage will add up to $100$, the percentage of other spam is $100-19+20+7+7+6+25+9=100-93=7$

Hence, the percentage of other spam is $7%$

The bar chart is drawn in excel by selecting the two columns of the above table.

## Part (c) Step 1: Explanation

When a phenomenon is broken down into sub-events and each event is represented in the diagram by a sub-component, the pie chart is utilized. Because there is no missing data, each category's number of spam is represented as a sector in a pie graphic.
