Among 436 workers surveyed in a Gallup poll, 192 said that it was seriously unethical to monitor employee e-mail. Among 121 senior-level managers, 40 said that it was seriously unethical to monitor employee e-mail. Consider the claim that for those saying that monitoring e-mail is seriously unethical, the proportion of workers is the same as the proportion of managers. Identify the test statistic and P-value. If using a 0.01 significance level, what should you conclude about the claim?
