 The Quality Assurance Department is anxious to improve the nominal value of the resistors to ensure 
more of them fall within the rated tolerance band. The manufacturing process is adjusted in an 
attempt to bring about this improvement. Following the adjustment, a further sample of 100 resistors 
is taken in order to determine if the adjustment has resulted in an improvement to the nominal value 
of the resistors. Analysing this second sample, it is noted that the mean value is now 21.8kΩ, with a 
standard deviation of 1kΩ
