The sign test is a nonparametric test that can be used to test either a claim involving matched pairs of sample data, a claim involving nominal data with two categories, or a claim about the population median against a hypothesized value
Formulate hypotheses and carry out a hypothesis test in the context of a single observation from a population which has a binomial distribution, using: direct evaluation of probabilities. a normal approximation to the binomial. Interpret outcomes of hypothesis tests in context.

Warning: These notes may contain factual and/or typographic errors.
We want an MP test at level . The likelihood ratio is
In the above example, we were able to extend our MP test for a simple hypothesis to a UMP test for a one-sided hypothesis. This phenomenon is not unique to exponential families. We can get the same behavior whenever the models have a so-called monotone likelihood ratio. De nition 2 (Families with monotone likelihood ratio (MLR)). We say that the fa...
