Let X denote the proportion of allotted time that a randomly selected student spends working on a certain aptitude test. Suppose the pdf of X is f(x; u) 5 5 (u 1 1)xu 0 # x # 1 0 otherwise where 21 , u. A random sample of ten students yields data x1 5 .92, x2 5 .79, x3 5 .90, x4 5 .65, x5 5 .86, x6 5 .47, x7 5 .73, x8 5 .97, x9 5 .94, x10 5 .77. a. Use the method of moments to obtain an estimator of u, and then compute the estimate for this data. b. Obtain the maximum likelihood estimator of u, and then compute the estimate for the given data

step-by-step explanation:

f

step-by-step explanation:

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft
