- 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 = 0.05.1. We poll 450 people and find that 30% favor Candidate S. In order to estimate with 90% confidence what percent of ALL voters would vote for Candidate S, we should use: 2-SampTInt 2-SampZInt 2-PropZInt TInterval 1-PropZInt ZInterval 2. We poll 550 people and find that 50% favor Candidate S. In order to estimate with 99% confidence the percent of ALL voters would vote for Candidate S, we should use: 2-PropZInt TInterval 2-SampZInt 2-SampTInt 1-PropZInt ZInterval5.

Pressing the lever to the right (R) produced no food reward. pressing the lever to the left (L) produced a single food pellet, and pressing the lever at the center (C) produced two food pellets. Because the center level produced the largest reward, the researcher hypothesized that the rat would press this lever most often. Each trial ended when the rat produced a level. The researcher recorded lever pressing for 30 trials.
