Q 7.2 Determine the value of 0 that minimizes average loss for the above choice of model and loss function. \begin{aligned} &\hat{\theta}=\frac{1}{n} \sum_{i=1}^{n}\left|y_{i}\right|\\ &\hat{\theta}=\frac{1}{n} \sum_{i=1}^{n} y_{i}^{2}\\ &\hat{\theta}=\frac{1}{n} \frac{1}{\sum_{i=1}^{n}\left|y_{i}\right|}\\ &\hat{\theta}=\frac{1}{n} \sum_{i=1}^{n} e^{\left|y_{i}\right|}\\ &\hat{\theta}=\frac{1}{n} \frac{1}{\sum_{i=1}^{n} y_{i}}\\ &\hat{\theta}=\frac{1}{n} \sum_{i=1}^{n} y_{i} \end{aligned}
