1. ## need help on cinfinence interval

Let $X_1,....,X_n$be a random sample of size n from a geometric distribution $Geo(p)$. Derive a conservative two-sided $100(1-\alpha)$% confidence interval for $p$ . Use equal-tails and give explicit expressions for $p_L$ and a $p_U$, where $p_L$ and $p_U$ are lower and upper confidence limites, respectively.
