A StatCrunch survey asked respondents how much time they spent daily on various social media sites. Is there a difference in the mean time spent on these social media sites? Use the following ANOVA output. Do a complete ANOVA analysis with a significance level of 0.05, including post hoc tests using the intervals given in the output. Assume that the Normality condition for the ANOVA is met, and for the purposes of this exercise treat the respondents as a random sample of all StatCrunch users.
