Answer 1

I believe that the smallest number of students Jimmy can measure is 223, and I know this is right because one of my teachers had us do this probem and she said this was it.

Answer 2

Answer: 223

Explanation:

• The census method is also known as a complete enumeration survey method where each and every individual in the given population is selected for the data collection.

Therefore, the SMALLEST number of students he must measure is the total number of students surveyed i.e. 223.

Hence, the SMALLEST number of students he must measure =223
