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 eachsit-in, as well as the number of student arrests. The data for 5sit-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 through d.

c. Give a practical interpretation of they-intercept of the least squares line. If a practical interpretation is notpossible, explain why.Choose the correct answer below.A.For each additional one dayduration, the number of arrests is estimated to change by the value of they-intercept.B.Since asit-in with 0 arrests is outside the range of the sampledata, they-intercept has no practical interpretation.C.Since asit-in with duration 0 is outside the range of the sampledata, they-intercept has no practical interpretation.D.For each additionalarrest, the duration is estimated to change by the value of the slope.

d. Give a practical interpretation of the slope of the least squares line. Over what range is the interpretationmeaningful?What is the best interpretation of theslope?A.Since asit-in with duration 0 is outside the range of the sampledata, the slope has no practical interpretation.B.Since asit-in with 0 arrests is outside the range of the sampledata, the slope has no practical interpretation.C.For each additionalarrest, the duration is estimated to change by the value of the slope.D.For each additional one dayduration, the number of arrests is estimated to increase by the value of the slope.

Over what range is the interpretationmeaningful?A.The interpretation is valid only forsit-ins with durations within the range of the sample data.B.The interpretation is valid for allsit-ins with the number of arrests greater than 0.C.The interpretation is valid for allsit-ins with durations greater than 0.D.The interpretation is valid only forsit-ins with the number of arrests within the range of the sample data.
