Question

A box has 3white(W) balls,2 black (B) balls and 4 red(R) balls. Two balls were drawn successively from this box (i) with replacement/ (ii) without replacement. Let X=the number of white balls drawn and let Y=the number of black balls drawn.

 

 

a.Give the joint p.d.f f(x,y) if the 2 balls are drawn with replacement?

d.Give the conditional p.d.f f(X|Y=0)) if the 2 balls are drawn with replacement?
excompute the Correlation p(X,Y) if the 2 balls are drawn with replacement?
f. If the number of balls of each color in the box areunknown and a random
sample of 30 balls drawn successively with replacement from this box yielded
the following data : 8 White balls, 5 black balls and 17 red balls.Test at (a=0.05)
the multinomial null hypothesis Ho: P(W)=0.3, P(B)=0.2 and P(R)=0.5.
using the sample data of part (f), give95% Confidence interval for the
proportion P(W) of white balls in the box?
