The horizontal axis is labeled Sample Number and ranges from 0 to 10. The vertical axis is labeled Sample Mean x bar and ranges from 122.75 to 124.50. The bottom line is labeled LCL and intersects the vertical axis at about 122.70. The middle line intersects the vertical axis at 123.50. The top line is labeled UCL and intersects the vertical axis at about 124.30. The entire region between the LCL line and the UCL line is shaded.
