Question
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. She
randomly 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 of
significance.
What are the null and alternative hypotheses?
0.081 versus H1:
Но р
(Type integers or decimals. Do not round.)
>
0.081
Веcause npo (1- Ро) %3D 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.
