A quality analyst has examined $20$ hotels around the state and found that $120$ customers in total have complaints about the various hotel services. Find the UCL and $LCL$ by using $3$sigma $)=(3.$ Hint: number of complaints is a counting type attributes data and the sample size $($the total number of total customers served$)$ is not known.

UCL$=0,LCL=13\mathrm{.}35$

UCL$=-1\mathrm{.}35,$ LCL$=13\mathrm{.}35$

Cannot be calculated

UCL$=13\mathrm{.}35,LCL=-1\mathrm{.}35$

UCL$=13\mathrm{.}35,LCL=0$
