6. Non-profit, part 3 - The researchers from Exercise 2 created a 95% two-proportion confidence interval for the difference in those who are \"highly satisfied\" when comparing people who work at non-profits to people who work at for-profit companies. Interpret the interval with a sentence in context. 95% confidence interval for p non-profits - p for-profits = (1.77%, 10.50%)

Solution

We are 95% confident that the true difefrence between the proportions of people who are highly satisfied with their work between non-profit and profit companies is between 1.77% and 10.50%.

As this whole interval is greater than 0%, then there is significant evidence at 0.025 level that there is a higher proportion of highly satisfied people in those who work at non-profit companies than those working in profit companies.
