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, bluegill, pike
112, 95, 210, 83
in the 5-year interval, did the distribution of fish change at the 0.05 level?
1. find the value of the chi-square statistic for the sample. (round the expected frequencies to at least three decimal places. round the test statistic to three decimal places.)
2. find or estimate the p- value of sample test statistic?
