Question

A survey asked national park visitors to choose their favorite type of landscape.

The results are shown in the following table.
(a)Find the percentage for each type of landscape.
Type of landscape Number of park visitors Percentage
Lakeside 8160
Jungle 8880
Desert 4800
Coast 2160

(b)Construct a percent bar graph for the data.New information provided by the student

Answer 1

We are asked to find the percentage of each type of landscape for the following table

To find the percentage, we have to sum over all the visitors to all the parks

`2400+9300+12000+6300=30000`

That is the parks received a total of 30000 visitors, to find the percentage of visitor that went to each particular class of park we have to divide the quantity of visitor that received that specific class of park over the total of 30000 visitors for all the parks. Let's do this for the Lakeside parks

`\text{ Percentage of visitor to Lakeside parks=}\frac{\text{ Total of visitor to Lakeside parks }}{\text{ Total of visitors to all the parks}}=(2400)/(30000)=0.08=8\%\text{ }`

Similarly, we construct the percentage of visitors for all the other types of parks, arriving in the following table

Where in each cell of the third column we have calculated the percentage by divided the second column by, 30000 and then multiplying by 100 to find the percentage

Part b) Percent Bart Graph

To construct a percent graph bar for the data, we will follow the following steps:

1) Construct a box with height the biggest of the percentage present on the table;

2) In the x- axis put labels, one for each type of park that you have in the table;

3) Make one bar over each label, the height of each bar is given by the percentage on the percentage column.

Let us apply these steps

1) Construct a box with height the biggest of the percentage present on the table;

3) Make one bar over each label, the height of each bar is given by the percentage on the percentage column.

Equivalently, we can represent this bar graph horizontally as follows
