please answer all parts using the data table provided thank you

The following table shows the sales of a product over a period of 7 weeks. Answer the following questions: 1.1 (5 points) Please make a forecast for week 10 using moving average (3). Please also calculate the mean absolution deviation (MAD) for this forecasting method 1.2 (5 points) Please make a forecast for week 10 using exponential smoothing (0.1). Please also calculate the mean absolution deviation (MAD) for this forecasting method. 1.3 (5 points) Using a Simple Linear Regression method, please make a prediction for period 10 (Hint: please use Anova table below to construct the equation for a fitted value). Please also calculate the mean absolution deviation (MAD) for this forecasting method. 1.3.1 (5 points) What % of variation in the data is explained by the model? 1.3.2 (10 points) What is the p-value of the slope (week)? Is there a significant relationship between demand and time (at =0.05 significance level)? \begin{tabular}{|r|r|} \hline & \\ \hline Week & Demand \\ \hline 1 & 9 \\ \hline 2 & 8 \\ \hline 3 & 9 \\ \hline 4 & 12 \\ \hline 5 & 9 \\ \hline 6 & 12 \\ \hline 7 & 11 \\ \hline \end{tabular} ES (0.1) Abs Error \begin{tabular}{|l|} \hline LR \\ Fited \\ Value Abs Error \\ \hline \end{tabular} Forecast Period 10 MAD
