Exit polling is a popular technique used to determine the outcome of an election prior to results being tallied. Suppose a referendum to increase funding for education is on the ballot in a large town (voting population over 100,000). An exit poll of 200 voters finds that 98 voted for the referendum. How likely are the results of your sample if the population proportion of voters in the town in favor of the referendum is 0.51? Based on your result, comment on the dangers of using exit polling to call elections. How likely are the results of your sample if the population proportion of voters in the town in favor of the referendum is 0.51? The probability that fewer than 98 people voted for the referendum is.

TV streaming subscription platforms have been taking over the entertainment industry. It is estimated that one-third of Filipinos qualify as "subscription streamers" i.e., those who watch streamed TV programs through a subscription service such as Netflix, Amazon Prime Video, or iflix. A recent poll included 2232 adult TV viewers, of which 785 are subscription streamers. Based on this result, can you conclude that the true fraction of adult TV viewers who are subscription streamers differs from one- third? Carry out the test using a Type l error rate of 0.05.
