The process engineer at Sival Electronics is also trying to determine whether a newer, more costly design involving a gold alloy in a computer chip is

more effective than the present, less expensive silicon design. She wants to obtain an effective output voltage at both high and low temperatures, when

tested with high and low signal strength. She hypothesizes that high signal strength will result in higher voltage output; low temperature will result in

higher output; and the gold alloy will result in higher output than the silicon material. She hopes that the main and interaction effects with the expensive

gold will be minimal. The data found below were gathered in testing of all combinations. What recommendation would you make?

Label each one of your interaction charts with the type of interaction being shown $($example: Signal x Material$)$
