Right after the poll stations are closed at 17:00, a politicalcandidate receives the
information that out of the 50 people interviewed her approval“count†is 24. As a statistics
lover, she immediately tests the null hypothesis that herpopulation approval rate is less than
or equal 0.50 against its respective alternative, at the 5% levelof statistical significance. What
is the conclusion of this test? Suppose in every consecutive 15minutes, number of people
interviewed increases by 5 and approval count increases by 4. Findthe earliest time, HH:MM,
that she can declare her victory based on her tests of hypotheses.Note that a formal
statistical/algebraic solution is expected with proper terminologyand notation.
