Question
Previously, 12.1% 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 80 workers and finds that 18 of them have a travel time to work that is more than 60
minutes. Test the economist's belief at the x = 0.1 level of significance.
What are the null and alternative hypotheses?
P =
0.121 versus H1: p
Ho: p
(Type integers or decimals. Do not round.)
>
0.121
Because npo (1- Po) =
< 10, the normal model may not be used to approximate the P-value.
(Round to one decimal place as needed.)
