A batch of thermometers have readings that are normally distributed with a mean of 0 degrees Celsius, and a standard deviation of 1 degree Celsius. If 12% of thermometers are rejected because their readings are too high, find the cut-off temperature.

A batch of thermometers have readings that are normally distributed with a mean of 0 degrees Celsius, and a standard deviation of 1 degree Celsius. If the top 6% of thermometers are rejected because they have readings that are too high, and the bottom 6% of thermometers are rejected because they have readings that are too low, what are the cut-off scores?
