Question

gemma is creating a histogram based on the table below.

salary range	number of people
$20,000 - $39,999	30
$40,000 - $59,999	35

which scale can she use for the vertical axis such that the difference in the heights of the bars is maximized?
o 0 - 50
o 0 - 40
o 10 - 50
o 25 - 40

Explanation:

Step1: Analyze data values

The number of people values are 40, 30, 35.

Step2: Evaluate each option

• Option 0 - 50: All values are well - spaced.
• Option 0 - 40: 40 will be at the top, others will be compressed.
• Option 10 - 50: The lower values will be very close together.
• Option 25 - 40: Most values will be bunched up.

The scale 0 - 50 will give the most spread out bars and thus maximize the difference in heights of the bars.

Answer:

0 - 50
