A team of researchers believe that millennials engage more in positive social media than baby boomers, including more likes, shares, and comments on posts that included positive language. After receiving consent from online participants, the researchers examined their history of Facebook activity and found that of the participants who engaged in at least 10 positive posts a week, 198 were millennials and 212 were baby boomers. Calculate χ 2 (chi-squared) to compare the proportion of millennials engaging in positive social media to the proportion of baby boomers.
