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© BrainMass Inc. brainmass.com June 3, 2020, 9:44 pm ad1c9bdddf
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 ...
The solution calculates the probability of the thermometer reading using the z-score and z-table.
