Assume that the wavelengths of photosynthetically active radiations (PAR) are uniformly distributed at integer nanometers in the red spectrum from 675 to 700 nm. What is the mean and variance of the wavelength distribution for this radiation? Round your answers to one decimal place (e.g. 98.7). Mean = Variance =

Step 1
The problem states that the wavelengths are "uniformly distributed at integer nanometers" from 675 to 700 nm. This indicates a discrete uniform distribution. Show more…

Assume that the wavelengths of photosynthetically active radiations (PAR) are uniformly distributed at integer nanometers in the red spectrum from 675 to $700 \mathrm{nm}$. (a) What is the mean and variance of the wavelength distribution for this radiation? (b) If the wavelengths are uniformly distributed at integer nanometers from 75 to 100 nanometers, how does the mean and variance of the wavelength distribution compare to the previous part? Explain.
