The readings on thermometers are normally distributed with a mean of 0°c and a standard deviation of 1.00°c
The distribution of readings on thermometer is standard normal.
The probability that selected thermometer reads greater than -0.16
P(z > -0.16) = 1- P(z < -0.16)
Using z score table to find probability below -0.16
P(z < -0.16) = 0.4364
P(z > -0.16) = 1- 0.4364
P(z > -0.16) = 0.5636
The probability that a randomly selected thermometer reads greater than negative 0.16 is 0.5636
