According to historical data, it is believed that 12% of American adults work more than one job. To investigate if this claim is still accurate, a random sample of 100 American adults is selected. It is discovered that 18 of them work more than one job. A researcher would like to know if the data provide convincing evidence that the true proportion of American adults who work more than one job differs from 12%. What are the values of the test statistic and P-value for this test?
Find the z-table here.
z = 1.85, P-value = 0.0322
z = –1.85, P-value = 0.0322
z = 1.85, P-value = 0.0644
z = –1.85, P-value = 0.0644
