A Researcher Wishes to Find Out Whether There Is a Dependable

question 118

Short Answer

A researcher wishes to find out whether there is a dependable relationship between the severity of earthquakes and temperature for the 7 days immediately preceding the quake. A sample of 10 measured earthquakes was randomly selected from those recorded since 1965. For each area both the Richter value (higher value meaning more severe quakes) and the mean temperature for the 7 days preceding the quakes were recorded. The data follow: $$\begin{array} { l c l } \text { Area } & \text { Richter Scale Value } & \text { Mean Temperature } \\\text { A } & 8.0 & 65 \\\text { B } & 7.0 & 67 \\\text { C } & 4.9 & 70 \\\text { D } & 6.5 & 66 \\\text { E } & 5.0 & 65 \\\text { F } & 5.5 & 60 \\\text { G } & 5.0 & 63 \\\text { H } & 4.5 & 64 \\\text { I } & 5.0 & 65 \\\text { J } & 2.0 & 65\end{array}$$ Neither distribution appears to be skewed.
-Calculate the correlation.
