Determine the Central Lines for Z and MW Charts and Draw

Determine the central lines for Z and MW charts and draw the charts. If the target X is 2.00 and the target R is 0.05, determine the plotted points for the following values. $$\begin{array} { c c } \text { Subgroup } & \text { Observed Value } \\1 & 2.05 \\2 & 2.08 \\3 & 1.97\end{array}$$
$\begin{array} { |l|l|l|l|l|l|l| l| }\hline \quad&\quad&\quad&\quad&\quad&\quad&\quad&\quad\\\hline \quad&\quad&\quad&\quad&\quad&\quad&\quad&\quad\\\hline \quad&\quad&\quad&\quad&\quad&\quad&\quad&\quad\\\hline \quad&\quad&\quad&\quad&\quad&\quad&\quad&\quad\\\hline \quad&\quad&\quad&\quad&\quad&\quad&\quad&\quad\\\hline \quad&\quad&\quad&\quad&\quad&\quad&\quad&\quad\\\hline \quad&\quad&\quad&\quad&\quad&\quad&\quad&\quad\\\hline \quad&\quad&\quad&\quad&\quad&\quad&\quad&\quad\\\hline \quad&\quad&\quad&\quad&\quad&\quad&\quad&\quad\\\hline \end{array}$
