The prevalence of Candida glabrata infection is found to be 80% in a population of 100. If the test is repeated for 95% confidence levels, then what will be the range of prevalence for the Candida glabrata infection?

The range obtained by repeating a test is given by the formula: p ± 2 √p (100-p) / n where, p = prevalence of the study as established from previous studies n = sample size used for the present study In this particular example, p = 80 n = 100. Hence, the range estimated would be = 80 ± 2 √80 (100-80) / 100 80 ± 2 x 4 80 ± 8 72 to 88
