Final answer:
Ruby's habit of being late and Javier's simple display of impatience don't provide sufficient evidence that they are both Type A personalities, which makes the statement false.
Step-by-step explanation:
The behavior of Ruby and Javier does not fully align with the characteristics of Type A personalities as defined by Friedman and Rosenman. Type A individuals exhibit traits such as an excessive competitive drive, a chronic sense of time urgency, impatience, and hostility, particularly towards those who delay them or do not meet their standards. Ruby's behavior of being habitually late because she tries to do just one more thing might suggest a procrastination issue or poor time management rather than the time urgency and impatience typically seen in Type A individuals. On the other hand, Javier's punctuality aligns with Type A characteristics, but his drumming fingers while waiting might suggest mere impatience rather than other Type A traits. Therefore, the statement that both Ruby and Javier are Type A personalities is false.
