-A producer of specialty products uses a variety of natural and man-made materials to
Make unique countertops for kitchens and baths. One product line mixes concrete and
Natural river stone to make countertops that are polished to a high shine revealing unique
Patterns. Occasionally coarse sand will result in undesirable pitting and rough spots on
Surfaces. Consequently, as part of its quality control efforts, 8 by 4 foot polished slabs
Are checked periodically for imperfections. For each slab inspected the number of
Imperfections (pits, rough spots, etc.) is recorded. What type of control chart should be
Used for these data?

A) Individuals chart
B) P-chart
C) C-chart
D) X-bar and R charts
