Given the Sample Data Below Construct a Scatter Diagram and Analyze

Short Answer

Given the sample data below construct a scatter diagram and analyze the results.
Temperature is the independent variable. $\begin{array}{lll}\text { Trial } & \text { Temp} & \text { Hardness }\\1 & 20^{0} \mathrm{C} & 35 \\2 & 25^{0} \mathrm{C} & 33 \\3 & 30^{0} \mathrm{C} & 28 \\4 & 35^{0} \mathrm{C} & 27 \\5 & 40^{0} \mathrm{C} & 23\end{array}$
$\begin{array} { |l|l|l|l|l|l|l| l| }\hline \quad&\quad&\quad&\quad&\quad&\quad&\quad&\quad\\\hline \quad&\quad&\quad&\quad&\quad&\quad&\quad&\quad\\\hline \quad&\quad&\quad&\quad&\quad&\quad&\quad&\quad\\\hline \quad&\quad&\quad&\quad&\quad&\quad&\quad&\quad\\\hline \quad&\quad&\quad&\quad&\quad&\quad&\quad&\quad\\\hline \quad&\quad&\quad&\quad&\quad&\quad&\quad&\quad\\\hline \quad&\quad&\quad&\quad&\quad&\quad&\quad&\quad\\\hline \quad&\quad&\quad&\quad&\quad&\quad&\quad&\quad\\\hline \quad&\quad&\quad&\quad&\quad&\quad&\quad&\quad\\\hline \end{array}$
