A researcher wanted to know if there is an age difference in the amount of time spent on social media. They collected data from 8 teenagers (13-18 years old) and 8 young adults (21-26 years old); they measured the average number of hours spent using all social media platforms over the course of a day. The mean hours spent on social media for teenage participants was 2.9750 with a variance of 1.0630 and the mean hours spent on social media for young adult participants was 2.1750 with a variance of 3.8931.
