An article in Chemosphere [“Statistical Evaluations Reflecting the Skewness in the Distribution of TCDD Level sin Human Adipose Tissue” (1987, Vol.16(8), pp. 2135-2140)] concluded that the levels of 2,3,7,8-TCDD (colorless persistent environmental contminants with no distinguishable odor at room temperature) in human adipose tissue has a lognormal distribution (based on empirical evidence from North America). The mean and variance of this lognormal distribution in the USA are 8 and 21, respectively.Let X denote this lognormal random variable. Determine the following:(a) P(2000 (b) Value exceeded with probability 10%(c) Mean and variance of X
