Question

Use the following data to answer the next five exercises: Two researchers are gathering data on hours of video games played by school-aged children and young adults. They each randomly sample different groups of 150 students from the same school. They collect the following data.

Researcher A concludes that most students play video games between four and six hours each week. Researcher B concludes that most students play video games between two and four hours each week. Who is correct?

Short answer

Both of the researchers are correct.

Step-by-step solution

Concept Introduction

The sample is a portion of the population that is chosen and analyzed in order to derive conclusions about the entire population of interest in statistics.

Explanation

The outcome depends on the nature of the samples. Each research results are true for their respective age groups because both researchers used a distinct sample, which may differ due to the age group included in the samples. As a result, we can infer that both researchers are correct.

Final answer

Both of the researchers are correct since the samples used for research differ.
