a$.$ The wind farm could be located on the large flat$-$topped hill to the east of the community $($Site WT$1),$ or on open land to the south of the community $($Site WT$2).$

The wind speed distribution at Site WT$1$ can be described by the Weibull distribution, where $k=5\mathrm{.}2$ and $A=12\mathrm{.}4.$

The wind speed distribution at Site WT$2$ can also be described by the Weibull distribution, where $k=2\mathrm{.}9$ and $A=10\mathrm{.}2.$

Estimate the median wind velocity at Sites WT$1$ and WT$2.$
