A study was done to compare the flu incidence rates at the sart and at the end of winter of a given year. A sample of 100 persons were asked for incidence of flu twice: once at the start and once at the end of winter. Sample data were as follows: . End of Winter Start of winter Yes No Yes.. 20 25 45 No 15 40 55 35 65 100 a.Give 92% Confidence Interval (CI) for incidence of flu rate(percentage) at the start of winter? b.Give 90% CI for the difference in flu incidence rates at the start and at the end of winter? c.Compute a measure of association between flue incidence at he start and at the end of winter?
