Ask the class to estimate how many hours on average they spend each day with smartphones, tablets, TV, radio, computers, and video games. Nielsen reported last year that people spent an average of 10 hr, 39 min each day with smartphones, tablets, TV, radio, computers, and video games. Have the class enter their data into the above calculator and conduct a two-tailed significance test to determine whether the difference between the class average and the general public is statistically significant.

Ask the class to report how much time they spent reading for personal interest over the previous weekend. The American Time Use Survey “collects data on the amount of time Americans age 15 and older spend reading for personal interest.” In 2015, the average amount of time Americans spent reading for personal interest on weekend days was 21 min per day. Have the class enter their data into the above calculator and conduct a two-tailed significance test to determine whether the difference between the class average and the general public is statistically significant.

Think of a simple question that you can post on social media to determine if you network differs from the general population

Think about a simple question you could ask your friends through social media. Before you ask the question, be sure to do some research and be sure you know the norms or the population average (note: you do not need the population SD--which is not typically reported in the media). Then, post you question online. Using the data your friends report, enter your data into the above calculator and conduct a two-tailed significance test to determine whether the difference between your network and the general public is statistically significant.
