Question
drag each letter based on the type of association shown by the corresponding graph or the association youd expect to see between the two variables.
a scatter plot b minutes since charging your phone and battery percentage remaining c scatter plot positive (with cg h written)
d the weight of a package and the cost to ship the package e scatter plot f the number of stains on a shirt and the original cost of the shirt negative (with a d written)
g scatter plot h a persons speed and the time it takes them to finish a race i scatter plot none (with b written)
drag these letters a - i
Step1: Analyze Positive Association
Positive association means as one variable increases, the other increases.
- C: The scatter plot shows upward trend (positive).
- D: Heavier package (weight) should cost more to ship (positive association, so D has positive).
- G: The scatter plot G has upward trend (positive).
- Wait, let's re - check:
- C: The plot C has points going up as x increases (positive).
- D: Weight of package and shipping cost: more weight → more cost (positive association, so D is positive? Wait, no, D is a description. Wait, the task is to drag letters (A - I) to Positive, Negative, None.
- Let's list each:
- A: Scatter plot with downward trend (negative).
- B: Minutes since charging (x) and battery percentage remaining (y): as minutes since charging increase, battery percentage remaining should decrease? Wait, no: if you start charging, minutes since charging start (x) and battery percentage (y): when charging, as time (x) increases, battery (y) increases? Wait, no, "minutes since charging your phone" – if you just finished charging, minutes since charging is 0, battery is 100. As minutes since charging increase (you use the phone), battery percentage decreases. So B has negative association? Wait, maybe I messed up.
- C: Scatter plot C: points go up as x increases (positive).
- D: Weight of package (x) and shipping cost (y): more weight → more cost (positive association, so D's association is positive. But D is a text box, not a plot. Wait, the letters are A (plot), B (text), C (plot), D (text), E (plot), F (text), G (plot), H (text), I (plot).
- E: Scatter plot E: points are scattered, no trend (none).
- F: Number of stains (x) and original cost (y): no association (none, because stains don't relate to original cost).
- G: Scatter plot G: upward trend (positive).
- H: Person's speed (x) and time to finish race (y): speed increases, time decreases (negative association).
- I: Scatter plot I: downward trend (negative).
So Positive association:
- C (plot with positive trend), D (weight and shipping cost: positive), G (plot with positive trend). Wait, but the "Positive" box should have letters where the association is positive.
- C: plot C has positive trend.
- D: weight and shipping cost: positive association (so D's association is positive).
- G: plot G has positive trend.
Wait, maybe the initial thought was wrong. Let's re - categorize:
- Positive (as one increases, the other increases):
- C: plot C (points go up).
- D: weight (x) and shipping cost (y): x↑→y↑ (positive).
- G: plot G (points go up).
- Negative (as one increases, the other decreases):
- A: plot A (points go down).
- B: minutes since charging (x) and battery percentage (y): x↑→y↓ (negative, because as time since charging (using phone) increases, battery drops).
- H: speed (x) and time (y): x↑→y↓ (negative).
- I: plot I (points go down).
- None (no association):
- E: plot E (scattered).
- F: stains and original cost (no association).
So Positive should have C, D, G? Wait, but the user's initial writing has "CG" and "H" in Positive? No, maybe I made a mistake. Let's look at the plots:
- A: plot A: downward trend (negative).
- C: plot C: upward trend (positive).
- G: plot G: upward trend (positive).
- D: text D: weight and shipping cost: positive association (so D's association is positive, so D should be in Positive.
Wait, maybe the correct Positive: C, D, G; Negative: A, B, H, I; None: E, F.
