Figure out if the following graph can be a "Cumulative Distribution Function (CDF)". If it can,...
he cumulative distribution function (cdf), F(z), of a discrete ran- om variable X with pmf f(x) is defined by F(x) P(X < x). Example: Suppose the random variable X has the following probability distribution: 123 45 fx 0.3 0.15 0.05 0.2 0.3 Find the cdf for this random variable
math 4. Let X be a random variable with the following cumulative distribution function (CDF): y <0 F(y) (a) What's P(X 2)? b) What's P(X > 2)? c) What's P(0.5<X 2.5)? (d) What's P(X 1)? (e) Let q be a number such that F()-0.6. What's q?
2). Consider a discrete random variable X whose cumulative distribution function (CDF) is given by 0 if x < 0 0.2 if 0 < x < 1 Ex(x) = {0.5 if 1 < x < 2 0.9 if 2 < x <3 11 if x > 3 a)Give the probability mass function of X, explicitly. b) Compute P(2 < X < 3). c) Compute P(x > 2). d) Compute P(X21|XS 2).

Sketch the following probability density function (pdf). Write an equation and sketch the corresponding Cumulative Distribution Function (CDF). Is this random variable discrete or continuous? Answer the following: P( V< -0.5 ) P( V < 1.0 ) P( V ≤ 1.0 ) fv(v)otherwise
I need the answer for (ii) 1. A certain continuous distribution has cumulative distribution function (CDF) given by F(a)-0, <0 where θ is an unknown parameter, θ > 0. Let X, be the sample miean and X(n) = max {Xu X2, ,..} 0) Show that n +, is an unbiased stimator of o Find its mean squnare error and check whether θι, is consistent for θ. (ii) Show that 2n- Xn) is a consistent estimator of fe (iii) Assume n...
y <0 1- e so y20 be the cumulative probability distribution function (CDF) for the random variable Y-> the size (square footage) of a house with respect to the number of toilets. Let X be the number of toilets in the houses with respect to the size (square footage). a) Give the probability distribution function (PDF) for the random variable X f(x)- f(x) houses with 2049 square feet? (use at least four digits after the decimal if rounding...) c) Plot...
