A certain party got 16.0 %of the votes in the last election. A new poll has been conducted,where 1000 randomly chosen people expressed which party they support. Out of them 170 said they support this party. (a) Calculate a confidence interval for the current support of this party in the population,using the confidence level 95 %. Use the normal approximation. For the standard deviation, use an estimate that is calculated from the sample proportion 0.17. (Do not use the conservative...

Right after the poll stations are closed at 17:00, a political candidate 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 her population approval rate is less than or equal 0.50 against its respective alternative, at the 5% level of statistical significance. What is the conclusion of this test? Suppose in every consecutive 15 minutes, number of people interviewed increases by 5 and...
