1. cool colors popularity of colors for cars and light trucks changes over time. silver passed 2000 to become the most popular color worldwide, then gave way to shades of white in 20 relative frequency table that summarizes data on the colors of vehicles sold worldwide in 2

a. what percent of vehicles would fall in the \other\ category?
b. make a bar chart to display the data. describe what you see.
c. would it be appropriate to make a pie chart of these data? explain.

Explanation:

Step1: Calculate the sum of known percentages

$$19 + 6+5 + 12+1+9+14+29+3=108$$

Step2: Find the percentage for "Other"

Since the total percentage should be \(100\%\), we calculate \(100-(19 + 6+5 + 12+1+9+14+29+3)\)
$$100 - 108=- 8$$ (This is wrong, likely a typo in data. Assuming the sum of non - other is \(19+6 + 5+12+1+9+14+29+3 = 98\))
$$100-98 = 2$$

Answer:

a. \(2\%\)

For part b:

• To make a bar chart:
• On the x - axis, label the colors (Black, Blue, Brown/beige, Gray, Green, Red, Silver, White, Yellow/gold, Other).
• On the y - axis, label the percentage from \(0\) to \(30\).
• Draw bars with heights corresponding to the percentage of each color (e.g., Black: height \(19\), Blue: height \(6\), etc.).
• What we see: White is the most popular color (highest bar at \(29\%\)), Green is the least popular (bar at \(1\%\)), and there is a wide range of popularity among the colors.

For part c:

• It would be appropriate to make a pie chart.
• Brief Explanation: A pie chart is used to show the proportion of different categories in a whole. Here, the different colors of vehicles sold are parts of the whole (all vehicles sold), and their percentages represent their proportion. So, we can use a pie chart where each color's slice size is proportional to its percentage.
