Question

The following is a list of the hourly rates for employees at a given company.

14.69, 30.52, 13.00, 37.00, 26.43, 44.34, 28.38, 42.63, 37.51, 53.62, 20.30, 26.42, 47.59, 31.46, 30.39, 35.20, 18.83, 26.21, 31.15, and 25.74.

The following classes are used in a table: 11.00 - 20.99, 21.00 - 30.99, 31.00 - 40.99, 41.00 - 50.99, and 51.00 - 60.99.

Which of the four graphs is a correct visualization for the data with the classes?

Answer 1

To visualize the data with the given classes, create a histogram. Each class interval will be represented by a bar, and the height of the bar represents the frequency/count of data points within that class.

Step-by-step explanation:

To visualize the data with the given classes, you need to create a histogram. A histogram is a chart that displays the distribution of data. Each class interval will be represented by a bar, and the height of the bar will represent the frequency or count of data points within that class.

Here are the steps to create the histogram:

1. Divide the data into the given class intervals.
2. Count the number of data points that fall within each class interval.
3. Plot a bar for each class interval, where the x-axis represents the class intervals and the y-axis represents the frequency.
4. The height of each bar indicates the frequency of data points within that class interval.
