G Let X1,··· ,Xn be iid from the Beta distribution Beta(α = 2,β = 2), which has pdf f (x) = 6 · x · (1 − x) for x ∈ [0, 1] and f (x) = 0 outside [0, 1]. Let F(x) be the cdf of Beta(α = 2,β = 2), and let. Fn(x) be the empirical cdf (EDF) based on the sample X1,··· ,Xn. (a) Find (by intergating the density) the cdf F (x). (b) Plot the curve F (x) using R over the range [0, 1]. (c) For a given x = 0.4, and n = 100, what is the mean (expectation) of the

Step-by-step explanation:

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.
