Data below shows counts of males and females in a sample population and the political party they voted for.

  • Create the observations matrix using the provided R syntax below
  • Select the appropriate statistical test,
  • Formulate the null hypothesis in your own words,
  • Compute the test statistic,
  • Find the critical value in Chi square table with the corresponding degrees of freedom
  • Find and interpret the statistical decision at the 0.01 significance level

# Gender and political affiliation

observed <- as.table(rbind(c(762, 327, 468), c(484, 239, 477)))

dimnames(observed) <- list(gender = c("F", "M"), party = c("Democrat","Independent", "Republican"))
