Educators are becoming increasingly concerned about the amount of time that teenagers are spending on social media and how it is affecting their performance in school. Education researchers would like to test, based on a sample size of \( n \), whether the average amount of time spent on social media by teenagers in high school is greater than 31 hours per week. Based on a previous study, the distribution of hours spent on social media by high school students in a one-week period is right-skewed. Which of the following are the appropriate assumptions for this test? Select one: Sample should be random and the sample size should be at least 30. Population should be random and the sample size should be at least 30. Population should be random and the successes/failures should be at least 10. Sample should be random and the successes/failures should be at least 10 .
