According to a government website, 42% of US citizens are Democrats, 34% are Republicans, and 24% are
Independents. A local municipality would like to know if the distribution of political party affiliation among its citizens
differs from the nationwide percentages. A random sample of 500 citizens of the municipality is selected. In the
sample, 200 were Democrats, 187 were Republicans, and 113 were Independents. What is the value of the chi-
square test statistic and P-value?
Find the chi-square table here.
O x2 = 2.48, P-value is between 0.10 and 0.15
O x = 2.48, P-value is greater than 0.25
O x2 = 2.58, P-value is between 0.10 and 0.15
O 2 = 2.58, P-value is greater than 0.25
