Question
Previously, 5.5% 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 60 workers and finds that 9 of them have a travel time to work that is more than 60 minutes. Test the economist's belief at the a = 0.05 level of
significance.
...
What are the null and alternative hypotheses?
0.055 versus H1: p
Ho: p
(Type integers or decimals. Do not round.)
>
0.055
%3D
Because npo (1- Po) =
10, the normal model
be used to approximate the P-value.
(Round to one decimal place as needed.)
