Given:

The histogram of a survey that represents the amount of electricity used by residents in a local community.

To find:

The approximate number of participants in the survey.

Solution:

Using the given histogram, we get the frequency table:

Electricity usage Frequency

50 23

150 34

250 25

350 26

450 42

Sum of frequencies is:


23+34+25+26+42=150

It means the total number of participants in the survey is 150.

Therefore, the correct option is (a).
