Assume that the readings on the thermometers are normally distributed with the mean of 0° and standard deviation of 1.00°C. Assume 2.5% of the thermometers are rejected because they have readings that are too high and another 2.5% are rejected because they have readings that are too low. Draw a sketch and find the two readings that are cutoff values separating the rejected thermometers from the others. Which graphs represent the region in which thermometers are rejected? The cutoff values are ______ degrees. (Use a comma to separate answers as needed. Round to two decimal places as needed)
