You work for a think tank that seeks to help people better balance their work and family lives. You suspect that part of the problem is that people are spending too much time commuting to work, which takes away time from their families. You decide to collect information on the annual person-hours of time (measured in actual hours) lost due to traffic congestion for 68 cities throughout the United States. You would like to examine both the average annual person-hours of time lost and the variation among the cities. Keep in mind that you have to present data which both include and exclude all outliers in your analysis.

(1) identify the sample (2) identify the variable(s) involved (3) identify the level of measurement for the variable(s) involved

(4) identify the independent and dependent variable(s) (if necessary) (5) identify AND explain which statistical analyses are most appropriate and why - please be as specific as possible
