SIMPLE LINEAR REGRESSION

Use all of the data, weeks $1-24,$ to calculate the regression equation for this data. Use the weeks $(1-24)$ as the independent variable $(x)$ and number of calls as the dependent variable $(y).$ Once you have the equation, forecast weeks $4$ through $24($enter $4,5,6,$ etc. as the $x$ value in the equation$).$ Calculate the MAD for this forecasting model. Comment on the goodness of fit $(R^2)$ and significance of the model $($F significance$)$ to determine if this forecast model should be included in the consideration of the different approaches. $($If the model is not significant, it cannot be considered, however, you must still make the forecasts and calculate the MAD$).$
