An NRC calibrated Farmer chamber was used to determine Ppol prior to a TG-61 in-air calibration. A reading was made at -300 V (the bias used for the calibration) resulting in a reading of -34.67 nC. A reading was made at +300 V resulting in a reading of -32.55 nC. Determine Ppol and comment on this value in the context of a calibration.

Calibrating a scale: Making sure that the scales used by businesses in the United States are accurate is the responsibility of the National Institute for Standards and Technology (NIST) in Washington, D.C. Suppose that NIST technicians are testing a scale by using a weight known to weigh exactly 1000 grams. The standard deviation for scale reading is known to be σ=3. . They weigh this weight on the scale 60 times and read the result each time. The 60 scale readings have a sample mean of x̄ =1000.8 grams. The calibration point is set too high if the mean scale reading is greater than 1000 grams. The technicians want to perform a hypothesis test to determine whether the calibration point is set too high. Use the α=0.05 level of significance and the P-value method with the TI-84 calculator. Determine whether to reject H0 the null hypothesis H0.
