Assume that the readings at freezing on a bundle of thermometers are normally distributed with a mean of 0C and a standard deviation of 1.00C. A single thermometer is randomly selected and tested.

If 3.2% of the thermometers are rejected because they have readings that are too high and another 3.2% are rejected because they have readings that are too low, find the two readings that are cutoff values separating the rejected thermometers from the others.

(Round answers to three decimal places when needed)
