Question

Let the random variable X have a discrete uniform distribution on the integers 8 sxs 15. Determine the mean, w, and variance, o, of X. Round your answers to two decimal places (e.g. 98.76). J = o2= Assume that the wavelengths of photosynthetically active radiations (PAR) are uniformly distributed at integer nanometers in the red spectrum from 620 to 655 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 =
