Separate random samples were collected by a polling agency to investigate the difference in employee satisfaction at non-profit organizations and at for-profit companies. Data collected from 433 employees at non-profit organizations revealed that 391 of them were "highly satisfied." From the for-profit companies, 426 out of 507 employees reported the s level of satisfaction. Researchers want to test if the proportions of satisfied employees are the same at for-profit compani- as at non-profit companies. Complete parts a through c below. P1 a) What is the difference in the proportions of the two types of companies? Assume p₁ is the proportion of satisfied non-p employees and p2 is the proportion of satisfied for-profit employees. The difference in the sample proportions, P₁-P2, is (Round to three decimal places as needed.)
