Sustainability in corporate culture is typically described as having three dimensions: economic, environmental, and social. The article “Development of Indicators for the Social Dimension of Sustainability in a U.S. Business Context” (J. of Cleaner Production 2019: 687–697) reported on the development of a survey instrument for the least-studied of these “three pillars,” social sustainability. The researchers had 26 experts take the final version of the survey. In each survey section, participants were asked to rank a set of possible metrics from most important to least important.
a. The four metrics listed below were categorized as “public actualization needs.” Use the mean ranks to test at the .05 significance level whether experts systematically prioritize some of these metrics over others with respect to social sustainability.

b. Repeat part (a) using the following survey metrics for “public safety and security needs.”
