A USA Today article claims that the proportion of people who
believe global warming is a serious issue is 0.5, but given the
number of people you've talked to about this same issue, you
believe it is greater than 0.5. The hypotheses for this test are
Null Hypothesis: p ≤ 0.5, Alternative Hypothesis: p > 0.5. You
take a random sample and perform a hypothesis test, getting a
p-value of 0.3256. What is the appropriate conclusion? Conclude at
the 5% level of significance.
