Question
Previously, 13.6% 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 12 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?
P =
Ho: p
0.136 versus H1:
0.136
p
>
(Type integers or decimals. Do not round.)
Because npo (1- Po)
< 10, the normal model may not be used to approximate the P-value.
(Round to one decimal place as needed.)
