If X is a binom. rand. var., for what value of θ is the probability b(x;n,θ) at max? Ive no idea... My only guess (most likely wrong) is that max and min are always derivatives... So do i just differentiate and express θ...? Any suggestions...?=( Thank you!

Ok, i think i got the second one.., but what do i do with 1/2 in front of 1/1+t and 1/1-t when i multiply them? Now the to first one. You mean i need to integrate it? Like this: Int[Z*(X-U)/S], but what range do i pick? And then var(Z) i can find from S^2=U'2-U^2 which is S=Sqrt[U'2-U^2] where...

Hi people! Im having problems with my Prob.Theor. assignment=( I was hoping that u might be able to help me... I have 2 problems that i ve no idea how to solve!Oo Heres 1st one We re given rand. var. X, its mean value U, the stand deviation S (sigma). We need to show that E(z)=0 and...

Thank you for the tips with Mathematica jackmell, I am sure going to need it! But the problem is that i have to do it by hand... Its not a computer based course, so if i encounter one of these on the exam, i won't be able to use Mathematica.. I know that the basic idea is that the solution...

Hi people! This is my first topic here so excuse me if I am doing smth wrong) So basically I am having problems with understanding of how to sketch the graphs of solutions of diff. eqs in terms of y and t... Here is the description and 2 problems: Problems 8 through 13 involve equations...
