You have been wondering whether the attention span of your classmates have gotten shorter because of too much screen time exposure. To confirm your hypothesis, you asked some of your classmates for a simple experiment and divided them into two groups. Group A became part of a 3-month exposure to screen for 1 hour daily whilst group B became part of 6 hours exposure to screen for 3 months as well asking them to finish your favorite K-dramas. Below are the measurements of their attention span in seconds whilst looking at a lagging screen of their professors before they say can't watch it. please show the computation.
