Previously, 8.1% of workers had a travel time to work of more than 60 minutes. An urban economist believes that the percentage has increased since then. Sherandomly selects 75 workers and finds that 8 of them have a travel time to work that is more than 60 minutes. Test the economist's belief at the a = 0.1 level ofsignificance.What are the null and alternative hypotheses?Họ: p0.081 versus H,: p0.081>(Type integers or decimals. Do not round.)Весause npo (1 - Ро) - 5.6< 10, the normal model may not be used to approximate the P-value.(Round to one decimal place as needed.)Find the P-value.P-value =(Round to three decimal places as needed.)

In a recent study, two treatments were compared to see which one helped symptoms of migraines. Of the 100 people who had treatment 1, 25 improved. Of the 100 people who received treatment 2, 39 improved. Is there a statistically significant difference in the proportions of patients who show improvement between treatments 1 and 2. Run the test at a 5% level of significance. 1) the appropriate null and alternative hypotheses; 2) the appropriate test; 3) the decision rule; 4) the calculation of the test statistic; and 5) your conclusion including a comparison to alpha or the critical value.
