Of the 2186 people who participated in the survey, 1312 indicated that they use social networking sites (such as Facebook and LinkedIn) to research job applicants. Based on the survey data, is there convincing evidence that fewer than two-thirds of hiring managers and HR professionals use social networking sites in this way? Use a significance level of = 0.01 to make your conclusion. 12. State the null and alternative hypotheses. 13. Determine the P-value of the test statistic. Round your answer to four decimal places. . Make the decision to reject or fail to reject the null hypothesis. State the conclusion of the hypothesis test.

Answer 1

n - 2186 x = 1312 p= ² = 1312 2186 = o. 6002 12. Ho: H: P = 0.6667 P < 0.6667 de Oo 13) Text statistic :- z = p - P - 0.6002 -0.6667 PU-P) 0.6667 (1-0.6667) 2186 z = - 6.597 < Zi=-7.33 P value = P(Z < < – 6.597) ZP = 0.00001 < 0.01 = 1 P = 0.0000 14) Reject Ho (mull hypothesis) There is sufficient evidence to test the claim that fewer than two-thirds of hiring managers and HR professionals use social networking sites.
