Question

The reaction time of a robot was measured for a similar sampleof 22 simulated malfunctions. The measurements, in nanoseconds,are 27.67   27.68   27.77 27.85 27.88 27.98 28.06 28.24 28.50 28.60 28.68 29.24   29.36   29.48 29.50 29.53 29.56 29.57 29.79 29.88 30.93 Estimate the population interquartile range.

Explanation / Answer

The given data withMinitab gives the following output,

Descriptive Statistics: Reaction time Variable         N       Q1      Median         Q3
Reaction time 21    27.930    28.680     29.545 The population interquartile range = Q3 -Q1 = 29.545 - 27.930 = 1.615
