An article in Journal of Hydrology [“Use of a Log normal Distribution Model for Estimating Soil Water Retention Curves from Particle-Size Distribution Data” (2006, Vol. 323(1), pp.325–334)] considered a lognormal distribution model to estimate water retention curves for a range of soil textures. The particle-size distribution (in centimeters) was modeled as a lognormal random variable X with ? = -3.8 and ? = 0.7. Determine the following:(a) P(X (b) Value for x such that P(X = x) = 0.95(c) Mean and variance of X
