Question

Data were collected that included information on the weight of the trash (in pounds) on the street for one week and the number of people who live in the house. The following figure shows a scatterplot with the regression line. a. Is the trend positive or negative? What does that mean? b. Now calculate the correlation between the weight of trash and the number of people. (Use $r$ -squared from the figure and take the square root of it.) c. Report the slope. For each additional person in the house, there are, on average, how many additional pounds of trash? d. Either report the intercept or explain why it is not appropriate to interpret it.
