A study of intra-observer variability in the assessment of cervical smears, 3,000 slides were screened for the presence or absence of abnormal squamous cells. Each slide was screened by a particular observer and then rescreened six months later by the same observer. The results are shown below. Test whether time of screening is related to the diagnosis. Was the observer more likely to detect squamous cells at one of the screenings? Use a 5% level of significance. 1) the appropriate null and alternative hypotheses; 2) the appropriate test; 3) the decision rule; 4) the calculation of the test statistic; and 5) your conclusion including a comparison to alpha or the critical value.
