Question Help ▼ Do people who work for non-profit organizations differ from those who work at for-profit companies when it comes to job satisfaction? Separate random samples were collected by a polling agency to investigate the difference. Data collected from 421 employees at non-profit organizations revealed that 369 of them were "somewhat satisfied." From the for-profit companies, 432 out of 518 employees reported the same level of satisfaction. Find the standard error of the difference in sample proportions. Let p, be the sample proportion of "somewhat satisfied" employees at non-profit organizations and p, be the sample proportion of "somewhat satisfied" employees from for-profit companies. The standard error of the difference in the two sample proportions is. (Round to four decimal places as needed.)
