An important factor in solid missile fuel is the particle size distribution. Significant prob- lems occur if the particle sizes are too large. From production data in the past, it has been determined that the particle size (in micrometers) distribution is characterized by 0, elsewhere. A Find the expected particle size. 8 Find E (x2) CFind the variance of the particle size. D Find the standard deviation of the particle size.
Answer Q4 only. 2. An important factor in solid missile fuel is the particle size distribution. Significant pro- blems occur if the particle sizes are too large. From production data in the past, it has been determined that the particle size (in micrometers) distribution is characterized by (5x-6, X >1, elsewhere. Find F(x). 3. Use the same probability distribution as in Question 2. What is the probability that a random particle from the manufactured fuel exceeds 3 micrometers? (You could...

Show that the mean X bar of a random sample of size n from a distribution having probability density function f(x;θ)=(1/θ)e-(x/θ) , ,0 < x < ∞ , 0 < θ < ∞ , zero elsewhere, is an unbiased estimator of θ and has variance θ2/n.
The joint distribution of two continuous random variables $X$ and $Y$ are given by: $f_{X,Y}(x,y) = Cxy$, for $0\leq x\leq y\leq 1$, and $0$ elsewhere. 1. Find $C$ to make $f_{X,Y}(x,y)$ a valid probability density function. Enter the numerical value of $C$ here: 2. What should be the correct PDF for $f_X(x)$: A. $f_X(x) = 2x$ for $0\leq x\leq 1$, and $0$ elsewhere. B. $f_X(x) = 3x^2$ for $0\leq x\leq 1$, and $0$ elsewhere. C. $f_X(x) = 4x(1-x^2)$ for $0\leq...
I only need an answer for the second question because I know 9/16 is incorrect. (1 point) Applicants for jobs at a call centre take two tests, one for communication skills and the other on IT skills, and normalized scores are recorded on each between 0 and 2. For a given applicant, let X be the score on the communications test and Y the score on the IT test. A model for the joint probability density function for the two...
