Question

When one thinks of the normal distribution, the first thing that comes to mind is the bell curve and grades. While this is one example of a normal curve that is widely recognized, it is not the only one. Come up with a unique normal distribution from literature that your classmates have not posted about already (for example, heights or shoe sizes). Explain your normal curve with items such as the mean and standard deviation. What do the areas in the intervals µ - σ to µ + σ, µ - 2σ to µ + 2σ and µ - 3σ to µ + 3σ represent with regard to areas under the normal curve? With the mean and standard deviation, calculate what the actual intervals are for your normal curve. Include any citations regarding where you obtained the data for your curve.

Answer 1

The mangroves of the North Pacific of Costa Rica are among the most altered coastal ecosystems in the country. The height of all species of mangrove tree is normally distributed with mean 8.8m and standard deviation 0.6m.

probability that the Mangrove tree height are 1 Standard deviation away from the mean is 0.6827

the probability that the Mangrove tree height is 2 Standard deviation away from the mean is 0.9545

the probability that the Mangrove tree height is 3 Standard deviation away from the mean is 0.9973
