D Question 13 4 pts 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 0.C (denoted by negative numbers) and some give readings above IC (denoted by positive numbers). Assume that the mean reading is I.C and the standard deviation of the readings is 1.DD.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. If 9% of the thermometers are rejected because they have readings that are too high, but all other thermometers are acceptable, find the temperature that line separates the rejected thermometers from the others.

A study of the amount of time it takes a mechanic to rebuild the transmission for a 2005 Chevrolet Cavalier shows that the mean is 8.4 hours and the standard deviation is 1.8 hours. If 40 mechanics are randomly selected, find the probability that their mean rebuild time exceeds 7.7 hours.
