A certain paper suggests the lognormal distribution as a model for SO2 concentration above a certain forest. Suppose the parameter values are α=1.9 and β=0.9. What is the expected value of the SO2 concentration?


-What is the standard deviation of the SO2 concentration?

-What is the probability that the SO2 concentration is at most 10?

-What is the probability that the SO2 concentration is between 5 and 10?

-What is the probability that the SO2 concentration is more than 9?

Question 1) The concentration, X, in ppm of chlorophyll in outfield grass be modeled as a gamma random variable with parameters α = 5 (α is called shape in R.) and β = 12 (β is called scale in R.). Thus, X has probability density: f(x,α,β) = 1 / β^αΓ(α) xα−1e−x/β for 0 ≤ x ≤ ∞ and 0 otherwise with α = 5 and β = 12 Note that Γ(α) is the gamma function. In R, there is a...

The Weibull distribution is widely used in statistical problems relating to aging of solid insulating materials subjected to aging and stress. Use this distribution as a model for time (in hours) to failure of solid insulating specimens subjected to AC voltage. The values of the parameters depend on the voltage and temperature; suppose α = 2.8 and β = 210. (a) What is the probability that a specimen's lifetime is at most 250? Less than 250? More than 300? (Round...
