Show the 4-Step Method in testing significance of mean difference in the following case:

The degree of clinical agreement among physicians on the presence or absence of generalized lymphadenopathy was assessed in 32 randomly selected participants from a prospective study of male sexual contacts of men with acquired immunodeficiency syndrome (AIDS) or an AIDS-related condition (ARC). The total number of palpable lymph nodes was assessed by each of three physicians. Results from two of the three physicians are presented in the table attached. Determine whether there is a systematic difference between the assessments of Doctor A vs. Doctor B using 1% level of significance.
