Please help me out with exact explanations..(How to do in TI-84 plus calculator!)

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 1.4% of the thermometers are rejected because they have readings that are too high and another 1.4% 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. interval of acceptable thermometer readings = 0.008 * C Round your answers to three decimal placesAssume that the readings at freezing on a batch of thermometers are normally distributed with a mean of OC and a standard deviation of 1.00 C. A single thermometer is randomly selected and tested. Find the probability of obtaining a reading less than -0.482.C. P(Z
