2.64 Pfeifer, Schubert, Liauw, and Emig (Trans IchemE, 2003) studied temperature measured when using different number of thermocouple holes. They set the reactor temperature to 310°

C and measured the temperature on the top cover plate of the reactor, using two different electric controls (grouping and single control)
of the heat cartridges. The number of thermocouple homes used and the temperatures recorded by the two controls are listed in table below.
a Make an appropriate plot to describe the temperatures recorded by the two controls when using different thermocouple holes.
b Describe any patterns observed from your plot.
c Compare the temperatures measured by the two different electric controls with each other as well as with respect to the temperature set.
