# probability of a reading that is between 2.00 and 2.34

Assume that the readings on the thermometers are normally distributed with a mean of 0 degrees and a standard deviation of 1 degrees C. A thermometer is randomly selected and tested. Find the probability of a reading that is between 2.00 and 2.34

#### Solution Preview

mean = 0, sd = 1

Find the z-score for x1 = 2.00 and x2 = 2.34

z1 =(x1 - mean)/sd = 2.00

z2 = (x2 - mean)/sd ...

#### Solution Summary

The solution calculates the probability of the thermometer reading using the z-score and z-table.
