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 how do i takcle this?

Question
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
how do i takcle this?
