lake with fish in the following proportions: 30% catfish, 15% bass, 40% bluegill, and 15% pike. Five years later it sampled the lake to see if the distribution of fish had changed. It found that the 500 fish in the sample were distributed as follows. Catfish Bass Bluegill Pike 118 77 226 79 A USE SALT In the 5-year interval, did the distribution of fish change at the 0.05 level? (a) What is the level of significance? 0.05 State the null and alternate hypotheses. Ho: The distributions are the same. H,: The distributions are different. Ho: The distributions are different. H,: The distributions are different. O Ho: The distributions are different. H,: The distributions are the same. : The distributions are the same. H,: The distributions are the same.
