(25.06) The popularity of computer, video, online, and virtual
reality games has raised concerns about their ability to negatively
impact youth. The data in this exercise are based on a recent
survey of 14- to 18- year- olds in Connecticut high schools.
Suppose the following are the grade distributions of boys who have
and have not played video games.
The null hypothesis "no relationship" says that in the
population of all 14- to 18- year-old boys in Connecticut, the
proportions who have each grade average are the same for those who
play and don't play video games.
Find the expected counts (±±0.01) if this hypothesis is true and
display them in a two-way table.
