This is my first year learning Prob. Stat. Please show me how to solve these questions. I have the answers, but I woullove to kndow how to get those answers. I will rate as soon as I see your comments. Thanks alot. Answers: a) k>0 b) F(x) = 1 - x^-k ; 11 Answers: a) F(x) = x^2 /9 ; 0< x <3 , zero if x<= 0, one if x>=3 b) 4/9 c) 1/4 d) 3 sqrt(2) / 2 e)2 Solution a) f(x) should be non-negative for all values hence, k>0. b) for CDF, integrate this function for x= 1 to infinity c) for k>1, it is giving some non-zero result and for k<1, it\'s zero in this case! 18) a)for cdf, integrate this function for x = 0to 3, we get : |(x^2)/9| for 0 to 3 => 2 b) integrate this function for x = 0to 2, we get : |(x^2)/9| for 0 to 2 => 4/9 c) integrate this function for x = 0 to 1.5 (as this is defined for x>0, we get : |(x^2)/9| for 0 to 1.5 => 1/4 d) intergrate this for x= 0tp m euuate it with intergation from x =m to 3.. find a m between 0 and 3 => 3 sqrt(2)/2 e) integrate xf(x) from x=0to 3 and it gives => 2.
