The Fish and Game Department stocked a 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 Bluegil Pike 124 95 210 71 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 Enter a number.
