Question 2 (1 point)

The central line on a p-chart is 0.50 with a UCL of 0.65 and an LCL of 0.35. The results of the next six samples are 0.60, 0.37, 0.45, 0.48, 0.45, and 0.42. What should you do?

Question 2 options:

	Nothing; the process is behaving as expected.

	Explore assignable causes because there is a run.
	Increase the sample size to get a better measure.
