Assuming that the sample size ( n = 23) is less than 10% of the population size (all available balls), so that we can assume sampling is without replacement, the binomial test is exact. You are testing H 0: p = 0.08 against H a: p > 0.08. Under H 0, the distribution of the number X of pink balls is X ∼ B i n o m ( n = 23, p = 0.08 ...

WebUse the binomial test when there are two possible outcomes. You know how many of each kind of outcome (traditionally called "success" and "failure") occurred in your experiment. You also have a hypothesis for what the true overall probability of "success" is. The binomial test answers this question: If the true probability of "success" is what ...
