Data were collected that included information on the weight of the trash (in pounds) on the street one week and the number of people who live in the house. The figure shows a scatterplot with the regression line. Complete parts (a) through (d) below. W Click the icon to view the scatterplot and the regression line a. Is the trend positive or negative? What does that mean? The trend is positive. As the number of people per household increases, the weight of trash tends to increase. b. Now calculate the correlation between the weight of trash and the number of people (Use R-Sq from the figure and take the square root of it.) (Round to two decimal places as needed.)

The output of a another regression analysis on the effect of radio advertising spending, television advertising spending and online advertising spending on sales is given below. For this study they explored 3 different types of advertising spending (radio, television and online). They modelled it as y = ao + a1¤1+a2x2 + a3X3. The table below gives the summary output of this regression analysis.
