Would the sample size be large enough if the population is school-aged children and young adults in the United States?

Short answer

The sample size would not be large enough if the population is school-aged children and young adults in the United States.

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

According to the rule of sample size, a sample must be a maximum of 10% of the population size. When compared to the population, which is the number of all students in the U.S., the sample size is negligible. As a result, the sample size of 150 students is insufficient.

Final answer

The sample size of 150 is insufficient if the population consists of all school-aged students and young adults in the country.
