DIFFICULTY AND TIMER STATISTICS
The graph represents the results of a survey taken by focus groups each shown a different version of an upcoming commercial for a sports car. Each version had a different amount of content showing the car in fast-driving scenes. After the group viewed the commercial, each member was asked two questions: "Did you feel that the car was sporty?" and "How likely are you to purchase this car?" The position of the circles on the left indicate how much fast-driving content (F) was in the version of the commercial show and the % of viewers who found the car to be 'sporty' (S). The relative size of the circles indicates how likely the members of the group were to purchase the car (L). The bigger the circle, the more likely they were to purchase.
Use the drop-down menus to fill in the blanks in each of the following statements based on the information given by the graph.
3. If the relationship between L and S were inversed, then were would be a correlation between F and L.
4. If the relationship between L and S were inversed, then were would be a correlation between S and L.

What the relationship between L and S were inversed means?
the relationship between them probably meant the change in size( the probability of a person buying the car) with respect to the increase in the s(y-axis) graph i.e. increase. so when the relationship is inversed then the greater the s or f index the smaller the circle (i.e. L) so the correlation would be negative for both.
As S increases and F increases, the size of the bubble i.e. L increases too. So L is positively correlated with both S and L.
If the relation between S and L were inversed, it would become negative correlation then. Select "negative" for statement 2.
If the relation between L and S were negative i.e. as S increases, L decreases (bubble size reduces), then as F increases L would decrease. So negative correlation. Select "negative" for statement 1.
