    Question Normal distribution

    A bunch of thermometers give a reading of 0 degrees C that follow a normal distribution with a mean 0 degrees C and a standard deviation of 1 degree C.

    Problem:
    If 3% of the thermometers are rejected because they have readings that are too high, and another 3% are rejected because they have readings that are to low, find the two readings that are cutoff values separating the rejected thermometers from the others?
