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.
A) 1.26
B)1.45
C)1.39
D)1.48
here as top 7 % readings will be at 93rd percentile , therefore temperature reading corresponding to the given information that separates the rejected thermometers from the others =1.48
option D is correct

Chapter 6 Test Name Tyler Sorkness The Precision Scientific Instrument Company manufactures thermometers that are supposed to give readings of 0°C at the freezing point of water. Assume that the mean reading is OPC and the standard deviation of the readings is 1.00°C. Assume that the temperatures are normally distributed. (Notice this is a standard normal distribution.) A thermometer is randomly selected and tested. For each question: a) sketch and shade the normal curve and b) find the appropriate probability....
