Assume that the readings on the thermometers are normally distributed with a mean of 0" and standard deviation of 1.00"C. Assume 2.9% of the thermometers are rejected because they have readings that are too high and another 2.9% 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. Click to view page 1 of the table. Click to view page 2 of the table.
