This can be seen in the figure where 19 of the 20 intervals (ie. 95%) include the 25% population prevalence, the exception being sample 16. In many public health applications we do not have t ...

For .05 and n 10 the critical value from the Lilliefors table is 0.2616. Since the largest deviation here is .1293, w ...
