Research Scenario: People can be classified into two categories: Type A personalities (hard-driving, competitive, and ambitious) and Type B personalities (relaxed and easy-going). Type A personalities also experience chronically high levels of frustration. To demonstrate this phenomenon, separate samples of Type A’s and Type B’s are obtained, with n=10 in each sample. They complete a frustration inventory measuring their level of frustration. The average score for the Type A’s is 82 with standard deviation of 11.9. The average score for the Type B’s is 71 with standard deviation of 10.2.

Type B's are more relaxed, easy going people.  One factor that differentiates these two groups is the   chronically high level of frustration experienced by Type A's, especially when doing statistical analyses.  (Oftentimes Type A's have been known to suffer from numerical alexithymia.) To verify this aspect separate samples of Type A's and Type B's are obtained. The following frustration scores were...
