A sociologist is conducting research about how often U.S. high school students engage with social media. She gathers a random sa
mple of 250 high school students from across the country and asks them how many times per week they engage with social media. The sample mean was 9.37 times per week with a sample standard deviation of 2.91. Construct the 95% Confidence Interval for the population mean number of times per week that U.S. high school students engage with social media. What is N in this sample?
