Answer
Total: 25 beetles; Average: 5 beetles per day

The correct answer is Total: 25 beetles; Average: 5 beetles per day — Thus the child saw 25 beetles in total and an average of 5 beetles each day.

Step-by-step solution

  1. Add all the daily counts: beetles.
  2. Divide the total by the number of days (5) to get the average: beetles per day.
  3. Thus the child saw 25 beetles in total and an average of 5 beetles each day.
Common mistake: Dividing by 4 instead of 5

Concept tested: Data analysis of ecological observations
