Assume that the readings on the thermometers are normally distributed with a mean of 0 degrees and standard deviation of 1.00degrees C. Assume 2.4% of the thermometers are rejected because they have readings that are too high and another 2.4% 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. A. The cutoff values are degrees. (Use a comma to separate answers as needed.
