A value has been measured by Instrument A 33
times with a standard deviation of 4.3. Another value
has been measured 7 times with Instrument B.
Within what range will the standard deviation of the
Instrument B observation have to fall to be
considered equivalent quality at a 95% confidence
level? Hint: Use the F-Distribution.
