A biologist is studying the composition of birds on a lake and counts 61 ducks, 17 geese, 11 cranes, 15 swans, and 6 herons. From previous studies performed around the same time of the year, she expects 50% of the birds to be ducks, 23% to be geese, 12% to be cranes, 10% to be swans, and 5% to be herons. What are the correct null and alternative hypotheses for performing a chi-square goodness of fit test? Select one. Null Hypothesis Ho: The distribution of birds observed does not follow the distribution from previous studies. Alternative Hypothesis H1: The distribution of birds observed follows the distribution from previous studies. Null Hypothesis Ho: The distribution of birds observed follows the Student's t- distribution. Alternative Hypothesis H7: The distribution of birds observed does not follow the Student's t-distribution. Null Hypothesis Ho: The distribution of birds observed follows the Normal distribution. Alternative Hypothesis H7: The distribution of birds observed does not follow the Normal distribution. Null Hypothesis Ho: The distribution of birds observed follows the distribution from previous studies. Alternative Hypothesis H1: The distribution of birds observed does not follow the diatri atudio
