The Accompanying Observations on X = Hydrogen Concentration (Ppm) Using

Essay

The accompanying observations on x = hydrogen concentration (ppm) using a gas chromatography method and y = concentration using a new sensor method were obtained in a recent study $$\begin{array}{l}\begin{array} { l l l l l l l l l l l } \hline x & 47 & 62 & 65 & 70 & 70 & 78 & 95 & 100 & 114 & 118 \\\hline y & 38 & 62 & 53 & 67 & 84 & 79 & 93 & 106 & 117 & 116 \\\hline\end{array}\\\\\begin{array} { l l l l l l l l l l l } \hline x & 124 & 127 & 140 & 140 & 140 & 150 & 152 & 164 & 198 & 221 \\\hline y & 127 & 114 & 134 & 139 & 142 & 156 & 149 & 154 & 200 & 215 \\\hline\end{array}\end{array}$$ Construct a scatter plot. Does there appear to be a very strong relationship between the two types of concentration measurements? Do the two methods appear to be measuring roughly the same quantity? Explain your reasoning.
