To minimize the potential for gastrointestinal disease outbreaks, all passenger cruise ships arriving at U$.$S$.$ ports are subject to unannounced sanitation inspections. Ships are rated on a scale of $0$ to $100$ points, depending on how well they meet the Centers for Disease Control and Prevention sanitation standards. In general, the lower the score, the lower the level of sanitation. A sample of international cruise ships was selected and yielded the sanitation inspection scores that can be found at the file: shipsanitation.txt $($which is available on our Quercus webpage$).$

Please do the following:

Step $1.$ Create a folder named sta$258.$

Step $2.$ Save shipsanitation.txt in the folder you created in Step $1.$ You will find shipsanitation.txt in our Quercus page.

Step $3.$ Launch R$.$

Step $4.$ Change working directory to sta$258($folder created in Step $1).$

Step $5.$ To import data into R$,$ please type the following command:

sanitation.score$=$read.table$($file$=$"shipsanitation.txt$",$header$=$TRUE$)$;

Using R$,$ make a boxplot for these data. Are there any outliers?
