For Problem $16\mathrm{.}11,$ follow steps outlined in example $16\mathrm{.}6$ perform a weighted least$-$squares adjustment of the network. Determine the weights based upon the given standard deviations. What are the $*($a$)$ Most probable values for the elevations of A and B$?($b$)$ Standard deviations of the adjusted elevations? $($c$)$ Standard deviation of unit weight? $($d$)$ Adjusted elevation differences and their residuals? $($e$)$ Standard deviation of the adjusted elevation differences?
