$(25$ points total$)$ An experiment was run in an effort to increase yield. Five factors, each at two levels, were studied. The factors $($and levels$)$ were $A=$ aperture setting $($small$,$ large$),B=$ exposure time $(20\%$ below nominal, $20\%$ above nominal$),C=$ development time $(30s,45s),D=$ mask dimension $($small$,$ large$),$ and $E=$ etch time $(14\mathrm{.}5$min,$15\mathrm{.}5$min. The unreplicated $2^5$ design shown below was run.
