Explanation:

Step1: Analyze the first set of data

For the first set of \(x - y\) values:

• As \(x\) values (\(40,50,90,300,320,380,390,570,700,800\)) do not show a clear increasing or decreasing trend with respect to \(y\) values (\(5,8,5,3,4,4,3,12,5,5\)).

Step2: Analyze the second set of data

For the second set of \(x - y\) values:

• As \(x\) values (\(2,2,3,6,7,18,69,75,88,97\)) increase, \(y\) values (\(0.5,0.5,0.5,0.5,0.4,0.4,0.2,0.2,0.1,0.1\)) decrease.

Answer:

1. No correlation.
2. Negative correlation.
