(Step-by-Step) Let X 1 , X 2 ,…, Xn be a random sample of size n from a normal distribution, Xi ~ N(μ ,σ ^2), and define U=∑limits_i=1^nX_i
Question: Let X 1 , X 2 ,…, Xn be a random sample of size n from a normal distribution, Xi ~ \(N\left( \mu ,{{\sigma }^{2}} \right)\), and define \(U=\sum\limits_{i=1}^{n}{{{X}_{i}}}\) and \(U=\sum\limits_{i=1}^{n}{X_{i}^{2}}\)
- Find a statistic that is a function of U and W and unbiased for the parameter \(\theta =2\mu -5{{\sigma }^{2}}\)
- Find a statistic that is unbiased for \({{\sigma }^{2}}+{{\mu }^{2}}\)
