Question
Previously, 8.8% of workers had a travel time to work of more than 60 minutes. An urban economist believes that the percentage has increased since then. She randomly selects 70 workers and finds that 10 of them have a travel time to work that is more than 60 minutes. Test the economist's belief at the α = 0.05 level of significance. What are the null and alternative hypotheses? Ho: p = 0.088 versus H₁ : (Type integers or decimals. Do not round.) р > 0.088 Because np。 (1-P) = 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.)
