Complete parts a and b below. Question content area bottom Part 1 a) Is there evidence that the percentage of construction workers who are illegal short-term immigrants differs in the two regions? Use alphaequals0.10. State the hypotheses for this test. Upper H 0: The distributions of worker type are the same for both regions. Upper H Subscript Upper A: The distributions of worker type are not the same for both regions. Part 2 Identify the test statistic for the appropriate chi-square test. chi squaredequals enter your response here (Round to two decimal places as needed.)
