Quizplus · Accepted Answer

The scatterplot of sales versus selling price shows a moderately negative linear relationship, indicating that the linearity condition is satisfied. However, the scatterplot of sales versus amount spent on advertising does not show a clear linear relationship, indicating that the linearity condition may not be satisfied. The nearly normal assumption and randomization condition are not applicable in this context.
