Module 13 Assignment Chi-square 1. One-variable chi-square: Table below shows the distribution of various ethnic groups in the population of a particular state based on a decennial U.S. census. Five years later a random sample of 2,500 residents of the state was taken, with the results given in the table (along with the probability distribution from the census year). Test, at the 1% level of significance (a=0.01), whether there is sufficient evidence in the sample to conclude that the distribution of ethnic groups in this state five years after the census had changed from that in the census year.
