The Precision Scientific Instrument Company manufactures thermometers that are supposed to give readings of O'C at the freezing point of water. Tests on a large
sample of these thermometers reveal that at the freezing point of water, some give readings below O C (denoted by negative numbers) and some give readings
above o'c (denoted by positive numbers). Assume that the mean reading is o 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. Find the temperature reading corresponding to the
given information.
Find Q3 the third quartile.
