Question

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. Find P34, the 34-percentile. This is the temperature reading separating the bottom 34% from the top 66%. P34 = °C

Answer 1

Refer Standard normal table/Z-table, Lookup for Z-value corresponding to area 0.34 to the left of the normal curve or use excel formula "=NORM.S.INV(0.34)" to find the Z-value.
