a$)$ A regional airline is concerned about its record of on$-$time performance. The Moncton hub

experiences $50$ flight operations each day of the week, with the record of on$-$time departures for the

previous $10$ days: $47,46,48,4546,34,49,47,48$ and $46.$ Prepare a $p$ chart with average on$-$time

departure percentage. The next day they had $43$ on time flights. Is this within acceptable limits$?$

b$)$ Police give speeding tickets to $34$ driverser month on a particular stretch of road. What type of

control chart would you use to monitor this process? Create the appropriate three$-$sigma control chart.

If they gave out fifty$-$seven tickets in a subsequent month $($with a similar level of enforcement effort$)$

would there be reason to believe that more people are speeding on that road? Why?
