The state of California is working very hard to ensure that all elementary age students whose native language is not English become proficient in English by the sixth grade. Their progress is monitored each year using the California English Language Development test. The results for two school districts in southern California for the 2003 school year are given in the accompanying table. Do the data indicate a significant difference in the 2003 proportions of students who are fluent in English for the two districts? Use α = .01.
