Data collected from 433 employees at non-profit organizationsrevealed that 391 of them were "highly satisfied." From the for-profit companies, 426 out of 507 employees reported the samelevel of satisfaction. Researchers want to test if the proportions of satisfied employees are the same at for-profit companiesas at non-profit companies. Complete parts a through c below.a) What is the difference in the proportions of the two types of companies? Assume p₁ is the proportion of satisfied non-profitemployees and p2 is the proportion of satisfied for-profit employees.P2The difference in the sample proportions, p₁ - P2, is(Round to three decimal places as needed.)
