Answer
Explanation:
Step1: Recall negative - correlation concept
In a negative correlation, as the value of (x) increases, the value of (y) decreases.
Step2: Analyze the first table
As (x) increases from 2 to 12 ((2,5,6,7,10,12)), (y) does not consistently decrease ((- 8,-5,-6,-3,-2,-1)).
Step3: Analyze the second table
(y=-5) for all values of (x), so there is no correlation.
Step4: Analyze the third table
As (x) increases from 2 to 6 ((2,5,6)), (y) decreases from 6 to 1 ((6,3,1)), and as (x) increases from 6 to 7, (y) stays the same ((1)), then as (x) increases from 7 to 12 ((7,10,12)), (y) increases from 1 to 6 ((1,3,6)). It does not show a consistent negative - correlation.
Step5: Analyze the fourth table
As (x) increases from 2 to 12 ((2,5,6,7,10,12)), (y) decreases from 4 to - 12 ((4,2,-4,-3,-11,-12)). This table shows a negative correlation.
Answer:
The fourth table (with (x = 2,5,6,7,10,12) and (y = 4,2,-4,-3,-11,-12)) shows a negative correlation.
