Suppose that and R charts based on subgroups of size 4 are being used to monitor the tire diameter of a new radial tire.The andR charts are found to be in statistical control with inches.A histogram of the tire diameter measurements indicates that these measurements are approximately normally distributed.If the tire diameter specifications are 50 inches ± 1 inch,is the process capable of meeting the specifications?
A)Yes
B)No
