Suppose all formulas are correctly entered. The simulation is run for $52$ periods. Then the total cost value $($cell F$3)$ from $200$ repetitions of the $52-$period simulation are captured in the area shown in cells I$5$ to J$205($the label "Sim #$"$ is in cell I$5).$

To determine the best order quantity, we wish to check how the simulation performs with different order quantities. A two$-$way data table is set up in cells M$5$ through R$205$ with order quantity values set to $40,60,80,100,$ and $120$ as shown in the highlighted area above.

Which of the following statements are true regarding the mean and standard deviations of the $200$ repetitions when considering the different order sizes $($cells N$1$ through R$2)?$
