Spartan Redl$-$Care has even gone so far as to adopt the slogan, "Get in$,$ Get better, Get out." As the facility manager, you have decided that thls slogan translates into an average customer wait time of $65$ minutes. You have collected the following data taken from a three$-$week perlod of typlcal demand:
