I want to know the answer and details step by step
Thank you so much
Transcribed Image Text:A new environmental policy is going to a general vote, and needs a "super majority" (over 67%) of
support to be implemented. Environmental scientists wants to test (before it goes to a vote), if the
proportion of voters is enough to implement this policy.
They collect data via surveys to 31 randomly selected voters. Specifically, the researcher wants to
test
Ho: p = 0.67 VS
Ha: p > 0.67
Note that p here denotes the proportion of voters who support this policy.
From the survey, the researcher found 25 people out of the 31 surveyed supported the policy, i.e.,
p=25/31.
Perform a hypothesis test with significance level a = 0.05. Be sure to check any assumptions, state
your rejection region, and provided a conclusion in context. What is the p-value for p?
