Hotels use statistical information from Xbar and S control charts to track their performance on a variety of indicators. Recently a hotel manager was asked whether or not his team is capable of maintaining scores between 8 and 10 (on a scale of 1 to 10) for "overall cleanliness of room". The most recent data for an n = 7 has a grand mean of 8.524, an overall standard deviation of 0.2, and an overall range of 1. Calculate Cp andCpk. Is the process capable of maintaining the scores? Why or why not?
