Now it is your turn: What is the minimum sample size we would need to be 95% certain that at least five people would test positives for disease B? First try n=610 : 1− Binomcdf (610,.0101,4)≈0.737. This value will be too small. Qext try n=950 : 1− Binomcdf (950,.0101,4)≈ 0.96277
​
. This value will be too large. Now see if you can find the quota; that is the minimum value of n so we can be just over 95% certain that at least five people will test positive for disease B? Quota value for n is
