Based on the 2000 Census, the proportion of the U.S. population falling into each of these four ethnic groups are 0.177 for
African-American, 0.032 for Asian, 0.734 for Caucasian, and 0.057 for Hispanic. Do the data provide sufficient evidence to
conclude that the proportions appearing in commercials are not the same as the census proportions? Test the relevant
hypotheses using a significance level of 0.01.
