Video games are played by both minors under the age of 18 and adults over the age of 18. Let us focus on the adult video game players. Records indicate that 42% of them are within the age of 18 – 25, 23% are within the age of 26 – 35, 17% are within the age of 36 – 45 and the remaining are 46 and older. Records also indicate that 72% of the video game players aged within 18 – 25 also play online, along with 53% of those aged 26 – 35, 33% are within the age of 36 – 45, and 42% of those that are 46 and older.(#’s 30 & 31)
(30) Determine the probability of selecting an adult video game players that are online players
(31) Determine the probability of selecting an adult video game player that is 46 and older given that such adult video game player does not play online

Video Games Forbidden Fruits for Youth" carried out an experiment
to determine if restrictive labels on video games actually
increased the attractiveness of the game for young game players.†
Participants read a description of a new video game and were asked
how much they wanted to play the game. The description also
included an age rating. Some participants read the description with
an age restrictive label of 71,...

Researchers are interested in testing whether a video game
increases brain activity. They plan to randomly assign subjects to
either the treatment group (15 minutes per day playing the game)
or a control group (15 minutes per day surfing the web). Because
they suspect that age might affect the outcome, the researchers
will create blocks of ages:
18-25,
26-35,
36-45,
and
46–55.
To randomly assign subjects to treatment or control, they will
place four tickets, labelled with the age groups,...

A study was conducted to investigate the influence of a driver's
age, number of driving years and attention span (the higher, the
more detailed) on the number of speeding tickets within the last
five years. Given a driver at age 30, who has been driving for 10
years with an attention span score of 5, what is the number of
tickets that can be expected?
