Solution
Assume that the mean reading is 0ºC and the standard deviation of the readings is 1.00ºC. Also assume that
the readings are normally distributed.
Interpretation. When tested at freezing, 2.5% of the thermometer readings will be equal to or less than –1.96°C, and another 2.5% of the thermometer readings will be equal to or greater than 1.96°C. Another interpretations is that 95% of all thermometer readings will be between –1.96°C and 1.96°C, at freezing point.
z = –1.96 °C, 1.96 °C
