Question: A survey of 900 people in federal prisons in the US showed that 67.3% were functionally illiterate. A survey of 900 people in prisons in Canada showed that 63.6% were functionally illiterate. Does the data indicate that there is a significant difference between the population proportion of US prisoners that are functionally illiterate and the population of Canadian prisoners that are functionally illiterate? Use a 5% level of significance.
