An article reported that the typical person spends one hour (60 minutes) per day accessing the Internet through a mobile device. A student wonders if males and females spend differing amounts of time per day accessing the Internet through a mobile device. The student selects a sample of 60 of friends and family (30 males and 30 females) and collects data about the time spent per day accessing the Internet through a mobile device (in minutes). The accompanying table contains these data.
