$1.$ Demand classification, for the given dataset $$ classify the demand patterns, identify all $4$ demand patterns, Smooth, Intermittent, Lumpy and Erratic. $-5$ points

a$.$ Use the limits of Coefficient of Variation squared $0\mathrm{.}49$ and ADI $1\mathrm{.}32$

b$.$ Use a more relaxed limits of Coefficient of Variation squared $0\mathrm{.}75$ and ADI $1\mathrm{.}8$

What is your interpretation of the difference between the classification schemes of $($a$)$ and $($b$)$
