Show that the following functions are probability density
functions for some value of k and determine k.
Then, determine the mean
((a),(c),(e),(g))
and variance
((b),(d),(f),(h))
of X. Round your answers to three decimal places (e.g.
98.765).
(a),(b)f (x) =
kx2 for 0 < x < 8
(c),(d)f (x) =
k(1 + 2x) for 0 < x < 21
(e),(f)f (x) =
ke-x for 0 < x
(g),(h)f (x) =
k where k > 0 and 121 < x < 121

Summarize key data distribution concepts including probability
mass functions (PMF), probability density functions (PDF), and
cumulative distribution functions (CDF). Based on an organization
or any organization you are most familiar with, provide an example
of a PMF, an example of a PDF, and an example of a CDF, based on
the type of data used in the organization. How would you summarize
each of these to someone who is not familiar with each of these
functions?

6) What are some density dependent and some density independent
factors that could together determine the carrying capacity of a
species? Be sure in your answer you make it clear which factors are
density dependent and which are density independent.

The random variables X and Y have the following probability
density function (pdf).
Conditional probability density function is
f(xly) = ax/y^2 , 0<x<y, 0<y<1
=0 , o/w
marginal density finction is
f(y) = by^4 ,0<y<1
= 0, o/w
At this time, find the constant a and b values to be the
probability density function, and then indicate whether the random
variables X and Y are independent, and if not, indicate whether
they are positive or inverse.

2 .Define the probability density functions (pdfs) of the
independent random variables X and Y as:
fX(x)={ (1/5).(1-(x/10)), 0≤x≤10 fY(y)={
(1/5).(y/10) , 0≤y≤10
0 , otherwise for both fX(x) and fY(y)
(a) Suppose that you are playing a game where you want to maximize
your number of points , and you can have your score be X or Y .
Which would you choose?

Show whether the following production functions exhibit increasing, constant, or decreasing returns to scale in K and L.
Show whether the following production functions exhibit
increasing, constant, or decreasing returns to scale in K and L.
Note: “exponents add up to one, so it CRTS” is not an acceptable
answer. a. Y=(K1-a + L1-a ) 1/a b. Y=K/L c. Y=K1/4L3/4
