Which situation involves inferential statistics?

Question

Which situation involves inferential statistics?

A. The food cans have a mean shelf life of 14 months.

B. The study estimates that 10% of the fish died as a result of the drought.

C. Gina answered 14 of 20 questions correctly.

D. The boxes have a mean weight of 3.3 kg and a standard deviation of 0.14 kg.

Answer 1

Inferential statistics uses the knowledge gained by the study of data to make educated guesses or predictions.

 

The mean and standard deviation are part of descriptive statistics, so we can eliminate answers A and D.  Answer C is also a part of descriptive statistics.

 

Answer B is an inference about the number of fish killed due to drought probably due to a survey and would be the best answer.
