What is the upper limit of the PDF y-axis? CDF y-axis? I think
it is infinity and 1 but I want to double check. Please also
explain conceptually why this is the case. I know the area under
the curve of PDF = CDF.
What is the difference between a pdf and a cdf? How are
they related?
Explain this as you would to someone who wasn't in class when I
did. Assume they have taken Calculus 2. You can use text, pictures,
a video, a dance, a song... whatever you want. Be creative! Submit
your explanation as one file (a pdf for text or
image, a single video or audio file etc.)
1) finding the volume of solid whose upper limit is the surface
f (x, y) = 4xe^y and which lower limit is the region r. where r is
the triangle limited by y = 2x; y = 2; x = 0.

let the continuous random variables X and Y have the joint
pdf:
f(x,y)=6x , 0<x<y<1
i) find the marginal pdf of X and Y respectively,
ii) the conditional pdf of Y given x, that is
fY|X(y|x),
iii) E(Y|x) and Corr(X,Y).
In a sample of n=3,600 students, the average GPA was x⎯⎯=3.5 with a sample variance of s2=0.25. Calculate the 98% confidence interval for the population GPA μ

Why can't I use the sum of force(about y axis) =0 at point P? I
used this method to get the tension in the cord at first of
solution, but gotten wrong answer.

What do you think...should there be a limit or cap on the
maximum amount that a jury awards a victim of medical
malpractice?
If Yes...why? If No...why not?
If good X is measured on the horizontal axis and good Y on the
vertical, what can you say about the preferences of someone whose
indifference curves are
parallel to the Y axis?
positively sloped with more desirable indifference curves as
one moves to the right?
negatively sloped with more desirable indifference curves as
one moves to the left?
L-shaped with one line of the L shape parallel to X axis and
the other line of the L shape parallel...
2. Let X be exponential with rate lambda. What is the pdf of Y =
X^0.5? How about Y = X^3? Contrast the complexity of this result to
transformation of a discrete random variable.
