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.

Would the sample size be large enough if the population is the students in the school?

As the population of the students is from the same school, the sample size is large enough.

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.

According to the rule of sample size, a sample must be a maximum of 10% of the population size. As a result, in this case, if the sample size is 150 students and the population consists solely of students from one school, the sample of 150 students is sufficient.

Hence, the sample size would be large enough if the population is the students in the school.
