A photomultiplier tube with a linear response to radiation registered 83.2 μA with a blank solution in the light path. Replacing the blank with the solution of interest lead to a response of 45.1 μA.

a) Calculate the percent transmission of this solution assuming zero dark current.
b) Calculate the percent transmission of this solution assuming 5.1 μA of dark current.
c) The absorbance of this solution assuming 5.1 μA of dark current.
d) The current from the photomultiplier tube with a solution that has one third of the concentration of the original solution.
e) The current from the photomultiplier tube if the blank shows 5.1 μA of dark current with the above solution?

A photometer with a linear response to radiation gave a reading of 690 mV with a blank in the light path and 101 mV when the blank was replaced by an absorbing solution. Calculate the transmittance and absorbance of the absorbing solution. Transmittance = Absorbance = the expected transmittance if the concentration of absorber is one half that of the original solution. Transmittance = the transmittance to be expected if the light path through the original solution is doubled. Transmittance...

A study considered the question, "Are you a registered voter?" Accuracy of response was confirmed by a check of city voting records. Two methods of survey were used: a face-to-face interview and a telephone interview. A random sample of 95 people were asked the voter registration question face to face. Of those sampled, eighty respondents gave accurate answers (as verified by city records). Another random sample of 82 people were asked the same question during a telephone interview. Of those...
