What are the correct null and alternative hypotheses for performing a chi-square goodness of fit test? Null hypothessis H0: The distribution of observed follows the distribution from previous studies. Alternative hypothesis H1: The distribution of birds observed does not follow the distribution from previous studies A university conducted a survey of its recent graduates.
