level for heart patients is 3.5.
True or False: A typical heart patient spends more time in the hospital than a typical
pneumonia patient. - Answer-False

Consider the following data conducted by Columbia Restaurants Association on
customer wait times at various fast food restaurants (minutes). We own two restaurants:
one in Vista and one in Five-Points, and following are results for the two locations:
Vista:
- Median = 10,
- 25th percentile = 7,
- 75th percentile = 12
Five-Points:
- Median = 7,
- 25th percentile = 4,
- 75th percentile = 13
Which restaurant should you visit if you want a more predictable service (measured by
wait time)? - Answer-Vista
- the IQR is much smaller for this location so it is more predictable.
(12-7 is less than 13-4)

- np-Chart
- X-bar and R Chart - Answer-np-chart

would you develop for tracking the variation in amount of beans filled at this location?
- X-bar and R Charts
- C-Chart
