(Solution Library) Suppose X_1, ..., X_10 are random variables with cero mean und variance 4 . Let Y=∑_π-1^10 X_n * If the random variables are independent,

Question: Suppose \(X_{1}, \ldots, X_{10}\) are random variables with cero mean und variance 4 . Let \(Y=\sum_{\pi-1}^{10} X_{n *}\)

  1. If the random variables are independent, what is the variance of \(S\) ?
  2. If \(\operatorname{Cov}\left(X_{i}, X_{j}\right)-2\) for \(i \neq j\), what is the variance of $S ?
  3. Use Chebyshev’s inequality to determine an upper bound for the probability of the event \(\{|S| \geq 10\}\) in both cases.
