A USA Today article claims that the proportion of people who
believe global warming is a serious issue is 0.73, but given the
number of people you've talked to about this same issue, you
believe it is different from 0.73. The hypotheses for this test are
Null Hypothesis: p = 0.73, Alternative Hypothesis: p ≠ 0.73. If you
randomly sample 21 people and 12 of them believe that global
warming is a serious issue, what is your test statistic and...
