A network server manufacturer tests the operating temperature of her new computer chips. Based on her tests, she assumes that the operating temperatures are normally distributed with mean temperature of 147 degrees F, with standard deviation of 2.4 degrees F.
Based on this information, 99.5% of the chips are expected to operate below what temperature (degrees F)

A network server manufacturer tests the operating temperature of her new computer chips. Based on her tests, she assumes that the operating temperatures are normally distributed with mean temperature of 110 degrees F, with standard deviation of 2 degrees F. Based on this information, 99.5% of the chips are expected to operate below what temperature (degrees F)?
A network server manufacturer tests the operating temperature of her new computer chips. Based on her tests, she assumes that the operating temperatures are normally distributed with mean temperature of 116 degrees F, with standard deviation of 2.9 degrees F. Based on this information, 99% of the chips are expected to operate below what temperature (degrees F)?
Healthy people have body temperatures that are normally distributed with a mean of 98.20 degrees Fahrenheit and a standard deviation of 0.62 degrees Fahrenheit. If a healthy person is randomly selected, what is the probability that he or she has a temperature above 98.8 degrees Fahrenheit? A hospital wants to select a minimum temperature for requiring further medical tests. What should the temperature be, if we want only 2.5% of healthy people to exceed it?
tests of a new light led to an estimated mean life of 1,321 hours and standard deviation of 106 hours. the manufacturer will advertise the lifetime of the bulb using the largest value for which it is expected that 90% of the will last at least that long. assuming bulb life is normally distributed,find that advertised value
Healty people have body temperatures that are normally distributed with a mean of 98.20∘F and a standard deviation of 0.62∘F . (a) If a healthy person is randomly selected, what is the probability that he or she has a temperature above 100∘F? (b) A hospital wants to select a minimum temperature for requiring further medical tests. What should that temperature be, if we want only 0.5 % of healty people to exceed it?
Healthy people have body temperatures that are normally distributed with a mean of 98.20∘F and a standard deviation of 0.62∘F. (a) If a healthy person is randomly selected, what is the probability that he or she has a temperature above 99.1∘F? answer: (b) A hospital wants to select a minimum temperature for requiring further medical tests. What should that temperature be, if we want only 1 % of healthy people to exceed it? answer:

A commercial bakery's ovens are designed to bake cakes at a
temperature of 350.0 °F. The ovens are calibrated so that their
temperatures should be normally distributed with a mean of 350.0 °F
and a standard deviation of 4.4 °F. During a recent inspection, the
bakery's quality control supervisor selected a random sample of 12
ovens and recorded their temperatures. She recorded her summary
statistics in the following table.
