Solved Exercise 4 20 If As In Exercise 4 16 Y Has Density Chegg 4.20 if, as in exercise 4.16, y has density function f (y)= { (1 2) (2−y),0,0≤y≤2 elsewhere find the mean and variance of y.4.16 let y possess a density function f (y)= {c (2−y),0,0≤y≤2 elsewhere a find c. b find f (y). c graph f (y) and f (y). d use f (y) in part (b) to find p (1≤y≤2). e use geometry and the graph for f (y) to calculate p (1≤y≤2). To find the mean and variance of the random variable y, you need to integrate y times the density function over the interval from 0 to 2 for the mean, and calculate the expected value of (y mean)^2 for the variance. the mean of the random variable y is 32 and the variance is 452.

Solved Exercise 4 20 If As In Exercise 4 16 Y Has Density Chegg If, as in exercise 4.16, y has density function f (y)= { [ (1 2) (2 y), amp; 0 ≤y ≤2; 0, amp; elsewhere ]. find the mean and variance of ywa. Find the mean and variance of y . exercise 4.16. let y possess a density function. a find c. b find f(y). c graph f (y) and f(y). d use f(y) in part (b) to find p(1 ≤ y ≤ 2). e use geometry and the graph for f (y) to calculate p(1 ≤ y ≤ 2). hence, the do you need an answer to a question different from the above? ask your question!. If, as in exercise 4.16, y has density function. in this case, the density function f (y) is only defined from 0 to 2, so we only need to integrate over this interval. thus, we have: e (y) = ∫ 0 2 y f (y) d y = ∫ 0 2 y ⋅ 1 2 (2 − y) d y = 1 2 ∫ 0 2 (2 y − y 2) d y show more…. 420 if as in exercise 416 y has density function fy.pdf download as a pdf or view online for free.
