Suppose that a car seatbelt manufacturer $-$ CS Tech, a supplier to major auto manufacturers, took seven samples in a $7-$hour shift $($meaning$,$ they are collecting one sample per hour$)$ of five seat belts to see whether the car seat buckle process is stastically stable. The data below was recorded on how long it takes for each seat belt to buckle up $($in seconds$).$ Its important for car manufacturers $($i$.$e$.,$ clients like Honda, GM or Ford$)$ that car seatbelts $($they are buying from CS Tech$)$ don't give hard time to customers.
