\textbf{Aufgabe 1}\\  $\mathbb{E}_\theta[\sum_{i=1}^{n}a_ix_i]=\sum_{i=1}^na_i\mathbb{E}_{\theta}[X_i]=\mathbb{E}_\theta[X_1]*\sum_{i=1}^na_i $\mathbb{E}_\theta[\sum_{i=1}^{n}a_ix_i]=\sum_{i=1}^na_i\mathbb{E}_{\theta}[X_i]=\mathbb{E}_\theta[X_1]*\sum_{i=1}^na_i\\  => \mathbb{E}_\theta[\sum_{i=1}^{n}a_ix_i]=\mathbb{E}_\theta[X_1] <=> \sum_{i=1}^na_i=1$
