The specifications for a refrigerator part $($in cm$)$ are $5\mathrm{.}00\backslash$pm $0\mathrm{.}10,$ and the Taguchi loss function is estimated to be L$($x$)=5,500($x $$ T$)2.$ Determine the estimated loss per part if the quality characteristic $($i$.$e$.,$ actual process performance$)$ under study takes on a value of $4\mathrm{.}91$ cm$.$

More than $$50$ but less than or equal to $$70$

More than $$70$ but less than or equal to $$90$

More than $$30$ but less than or equal to $$50$
