10.63) In material sciences, measuring temperatures accurately is of great importance. Optical pyrometry is an established method used for measuring temperatures. These pyrometric temperature measurements are affected by the selection of operating wavelength and atmospheric conditions. To solve some of the measurement problems, Rohner and Newmann developed a new system based on UV-B (ultraviolet) wavelength range for pyrometry and tested it on a blackbody without solar irradiation. They recorded the percentage of deviation of the UV temperatures from the blackbody temperatures. Two sets of data were collected; one based on the calibration at 1400 degrees C and the other at 1500 degrees C. The data are shown in the attached image. Is the mean percent deviation significantly higher at 1500 degrees C? Use α = 0.05.
