**Question** **12 Correct Mark 1.00 out of 1.00**

**The Precision Scientific Instrument Company manufactures thermometers that are supposed to give readings of **** 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 **** (denoted by negative numbers) and some give readin****bove **** (denoted by positive numbers). Assume that the mean reading is **** and the standard deviation of the readings is **** 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.**

If 7% of the thermometers are rejected because they have readings that are too high, but all other thermometers are acceptable, find the temperature that separates the rejected thermometers from the others
