The statement that is true is that there are two categories of control charts: one for monitoring attributes and the other for monitoring variables. P-charts and c-charts are actually specific types of control charts used for monitoring proportions and counts of defects in a process, and are not tied to specific industries such as manufacturing or services. The statement about monitoring signals, control attributes, and noise factors is not accurate in terms of categories of control charts, but may refer to specific applications or types of control charts within those categories.
