Four students conducted the same science fair project to determine the battery life of a specific brand of batteries. Alice tested 4 batteries. Justin tested 18 batteries. Katarina tested 8 batteries. Noah tested 5 batteries. Which student's data would be most representative of the brand's battery life?

Answer: Justin

Step-by-step explanation:

In statistics, the accuracy and reliability for any study mainly depends on the sample size taken out of the entire population.

Larger the size of the sample gives more accurate and reliable results.

Given : Four students conducted the same science fair project to determine the battery life of a specific brand of batteries.

Alice tested 4 batteries.

Justin tested 18 batteries.

Katarina tested 8 batteries.

Noah tested 5 batteries.

From all of the 4 students, Justin look the largest sample size to test the batteries.

Therefore, Justin's data would be most representative of the brand's battery life.

I believe it would be Justin because he tried out the most amount of batteries
