Question
Trees are subjected to different levels of carbon dioxide atmosphere with 6% of them in a minimal growth condition at 350 parts per million (ppm), 10% at 450 ppm (slow growth), 47% at 550 ppm (moderate growth), and 37% at 650 ppm (rapid growth). ) Determine the probability mass function of the carbon dioxide atmosphere (in ppm) for these trees in ppm? Part B) Determine the cumulative distribution function of the carbon dioxide atmosphere (in ppm) for these trees in ppm? Part C) What is the mean of the carbon dioxide atmosphere (in ppm) for these trees in ppm? 479 565 630 390Explanation / Answer
