Assume that the readings at freezing on a batch of thermometers are normally distributed with a mean of 0°C and a standard deviation of 1.00°C. A single thermometer is randomly selected and tested. If 2.7% of the thermometers are rejected because they have readings that are too high and another 2.7% 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. Please round answers to 3 decimal places. interval of acceptable thermometer readings = ________°C
