College protests of labor exploitation. The United Students Against Sweatshops (USAS) was formed by students on U.S. and Canadian college campuses in 1999 to protest labor exploitation in the apparel industry. Clark University sociologist Robert Ross analyzed the USAS movement in the Journal of World-Systems Research (Winter 2004).

Between 1999 and 2000, there were 18 student “sit-ins” for a “sweat-free campus” organized at several universities. The following table gives the duration (in days) of each sit-in, as well as the number of student arrests.

a. Do the data support the theory that sit-ins of longer duratian are more likely to lead to arrests? Support your answer with a graph.

b. Repeat part

a, but graph only the data for sit-ins in which there was at least one arrest. Do you detect a trend?

c. Comment on the reliability of the trend you detected in part b.
