The police department tracked the number of ticket writers and number of tickets issued for the past 8 weeks. The scatterplot shows the results. Based on the scatter plot, which statement is true?

• There were 50 tickets issued every week.

• More ticket writers results in fewer tickets issued.

• More ticket writers results in more tickets issued.

• When there are 10 ticket writers, there will be 800 tickets issued.

Which data will most likely show a negative correlation when graphed on a scatterplot?

• The outside temperature and the number of people wearing gloves

• A student's height and grade point average

• The distance a student lives from school and the amount of time it takes to get to school

• The number of visitors at an amusement park and the length of the lines for the rides
