Chapter SR34, Problem 5P

Solution

Draw a histogram to display the data. Begin with the interval $5.00 to $6.99.

Histogram drawn below.

Given:

Use the following list of hourly wages of employees to answer Exercise - $8.50, $6, $10, $14.25, $5.75, $7, $6.50, $14, $10, $9, $6.50, $8.25, $8.50, $11.25, $7, $16, $12, $6, $6.75.

Concept used:

• A histogram is a display of statistical information that uses rectangles to show the frequency of data items in successive numerical intervals of equal size.
• It is difficult to analyze unorganized data, it is helpful to organize data using a line plot, stem-and-leaf plot, histogram, or box-and-whisker plot.

Calculation:

The given list of hourly wages of employee - $8.50, $6, $10, $14.25, $5.75, $7, $6.50, $14, $10, $9, $6.50, $8.25, $8.50, $11.25, $7, $16, $12, $6, $6.75.

First make a frequency table -
