8 Results from a civil servant exam are shown in the table to the right. Is there sufficient evidence to support the claim that the results from the test are discriminatory? Use a 0.05 significance level. Determine the null and alternative hypotheses. O A. Ho: White and minority candidates do not have the same chance of passing the test. H₁: White and minority candidates have the same chance of passing the test. O B. Ho: A white candidate is more likely to pass the test than a minority candidate. H₁ A white candidate is not more likely to pass the test than a minority candidate. O C. Ho: A white candidate is not more likely to pass the test than a minority candidate. H₁: A white candidate is more likely to pass the test than a minority candidate. O D. Ho White and minority candidates have the same chance of passing the test. H₁: White and minority candidates do not have the same chance of passing the test. Determine the test statistic x² = (Round to three decimal places as needed.) Determine the P-value of the test statistic. P-value = (Round to four decimal places as needed.) Is there sufficient evidence to support the claim that the results from the test are discriminatory? O A. There is not sufficient evidence to reject the claim that a white candidate is more likely to pass the test than a minority candidate OB. There is sufficient evidence to reject the claim that a white candidate is more likely to pass the test than a minority candidate. OC. There is not sufficient evidence to support the claim that the results are discriminatory. OD. There is sufficient evidence to support the claim that the results are discriminatory.
