The class interval width for the distribution that we have here is given as $30000. The six midpoints and the class boundaries have being calculated below.

How to solve for the class boundary

238,000 - 58,000= 180000

180000 / 6 = 30000

Class Boundaries

1 58000 but less than 88,000

2 88,000 but less than 118,000

3 118,000 but less than 148,000

4 148,000 but less than 178,000

5 178,000 but less than 208,000

6 208,000 but less than 238,000

What is the class interval width?

238,000 - 58,000= 180000

180000 / 6 = 30000

width = 30000

The six class midpoints

  • 58000 + 88000 / 2 = 73000
  • 88000 + 118000 / 2 = 103,000
  • 118000 + 148000 / 2 = 133,000
  • 148000 + 178000 / 2 = 163000
  • 178000 + 208000 / 2 = 193000
  • 208000 + 238000 / 2 = 223000
