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 d.

a. Use the results of the linear regression to find the least squares prediction equation.

b. Give a practical interpretation of the y-intercept of the least squares line. If a practical interpretation is not possible, explain why.Choose the correct answer below.A. Since a sit-in with 0 arrests is outside the range of the sample data, the y-intercept has no practical interpretation.B. For each additional one day duration, the number of arrests is estimated to change by the value of the y-intercept.C. For each additional arrest, the duration is estimated to change by the value of the slope. D.Since a sit-in with duration 0 is outside the range of the sample data, the y-intercept has no practical interpretation.

c.Give a practical interpretation of the slope of the least squares line. Over what range is the interpretation meaningful?What is the best interpretation of the slope?A. For each additional one day duration, the number of arrests is estimated to increase by the value of the slope. B. Since a sit-in with 0 arrests is outside the range of the sample data, the slope has no practical interpretation.C. For each additional arrest, the duration is estimated to change by the value of the slope.D. Since a sit-in with duration 0 is outside the range of the sample data, the slope has no practical interpretation. Over what range is the interpretation meaningful?A. The interpretation is valid for all sit-ins with the number of arrests greater than 0.B. The interpretation is valid only for sit-ins with durations within the range of the sample data.C. The interpretation is valid for all sit-ins with durations greater than 0.D.The interpretation is valid only for sit-ins with the number of arrests within the range of the sample data.
