Trouble was being experienced by a new high-tech machine for joining two pieces of sheet metal. The two factors considered first are the pressure (low/high) and temperature of the pump low/high. The response is the diameter \((\mathrm{mm})\) of a button-shaped joint which is an indirect measure of strength.

Interpret the effects based on confidence intervals.
