An association was formed by students to protest labor
exploitation in the apparel industry. There were 18
student "sit-ins" for a "sweat-free campus" organized
at several universities. Data were collected for the
duration (in days) of each sit-in, as well as the
number of student arrests. The data for 5 sit-ins in which
there was at least one arrest and the results of a simple linear
regression are found below. Let y be the number of arrests and x be
the duration. Complete parts a through
c.
