A manufacturing company in Izmir produces thermometers with a brand new technology. Experiments for precision are held with large samples. As a result of these experiments, at the freezing point of water, some thermometers give readings below 0°C which are denoted by negative numbers and some give readings above 0°C which are denoted by positive numbers. Assume that the mean reading is 0°C and the standard deviation of the readings is 1.00°C. Also assume that the frequency distribution of errors closely resembles the normal distribution. A thermometer is randomly selected and tested. A quality control analyst wants to examine thermometers that give readings in the bottom 4%. Find the temperature reading that separates the bottom 4% from the others. Round to two decimal places. O A. -1.48° O B. -1.75 OC. -1.89° OD. -1.63°
