Business analytics any help would be great! What type of pattern exists in the data?

Select your answer $-V$

$($b$)$ Develop a three$-$week moving average for this time series. Compute MSE and a forecast for week $7.$

Do not round intermediate calculations. If required, round your answers to two decimal places.

$\backslash$table$[[$Week$,$Value,Forecast$],[1,18,],[2,15,],[3,15,],[4,13,],[5,17,],[6,14,]]$

MSE: $$

The forecast for week $7$ : $$

$($c$)$ Use $=0\mathrm{.}2$ to compute the exponential smoothing values for the time series. Compute MSE and a forecast for week $7.$

Do not round intermediate calculations. If required, round your answers to two decimal places.

$\backslash$table$[[$Week$,$Value,Forecast$],[1,18,],[2,15,],[3,15,],[4,13,],[5,17,],[6,14,]]$

MSE:

The forecast for week $7$ : $$

$($d$)$ Compare the three$-$week moving average forecast with the exponential smoothing forecast using $a=0\mathrm{.}2.$ Which appears to provide the better
