Q$1.$ Professor Choi at Meredith College wants to forecast the number of students operations management next semester in order to determine how many sections to schedule. He has accumulated the following enrollment data for the past six semesters:

$\backslash$table$[[$SEMESTER$,$STUDENTS ENROLLED IN OM$],[1,290],[2,340],[3,320],[4,360],[5,330],[6,370]]$

decim

$b(4$ pts$).$ Compute the exponentially smoothed forecast $)=(0\mathrm{.}3($Model B$)$ for semesters $\frac{?}{{?}_{?}}$ umuugn $7($Use two decimals$).($Assuming that the exponential smoothing model for semester $1$ is $290.)$

$\backslash$table$[[$SEMESTER$,$Exponentially smoothed forecast $)=(0\mathrm{.}3$ for semesters $1$ through $7],[1,290],[2,],[3,],[4,],[5,],[6,],[7,]]$

$(4$ pts$).$ Calculate the accuracy of two model $($A and B$)$ using MAD $($Using two decimals$)($from semest $4$ to $6$
