A. A spectrophotometer is known to have 0.800% stray light reach the detector for all analyses due to poor light sealing. Determine the true absorbance, apparent absorbance, and apparent transmittance for a sample with a true transmittance of 0.0657.

B. What amount of stray light produces an apparent absorbance of 1.995 with a true transmittance of 0.0100?

C. In the process of performing an analysis, you determine that you need to improve the precision by limiting the error in the absorbance to 0.00007200. You attempt to achieve this by reducing the amount of stray light that reaches the detector. What is the maximum amount of stray light that can reach the detector that will limit the error in the absorbance to 0.00007200 for a true absorbance of 1.1000000?

Consider a simple spectrophotometer with a diode array detector to collect a simultaneous visible light spectrum versus a more expensive double beam spectrophotometer that is capable of measuring in the ultraviolet and visible spectrum, in which a diode array detector is extremely rare. There are 2 major reasons why, based on the components of an instrument. What are they? Explain your reasoning. Basically, it's asking why diode array detectors are rare in a double beam instrument. One reason should be...

The population of all verbal GRE scores are known to have a standard deviation of 8.5. The UW Psychology department hopes to receive applicants with a verbal GRE scores over 210. This year, the mean verbal GRE scores for the 42 applicants was 212.79. Using a value of α = 0.05 is this new mean significantly greater than the desired mean of 210? a. Is this a one tailed or two tailed test? Why? b. Conduct the appropriate hypothesis test...
