24- The marketing manager for an automobile manufacturer is interested in determining the proportion of new compact-car owners who would have purchased a GPS navigation system if it had been available for an additional cost of $300. The manager believes from previous information that the proportion is 0.30. Suppose that a survey of 200 new compact-car owners is selected and 79 indicate that they would have purchased the GPS navigation system. If you were to conduct a test to determine whether there is evidence that the proportion is different from 0.30 and decided not to reject the null hypothesis, what conclusion could you reach? a) There is insufficient evidence that the proportion is 0.30. b) There is not sufficient evidence that the proportion is not 0.30. C) There is sufficient evidence that the proportion is 0.30. There is not sufficient evidence that the proportion is 0.30.

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. (1) Critical Values (Round off to 3 decimal places): (2) Test Statistic (Round off to 2 decimal places): (3) Conclusion: (Type 'Reiect HO' or 'Fail to Reiect HO')
A researcher wants to determine the percentage of American teenagers who send or receive text messages while doing homework. Which of the following techniques would likely be the MOST efficient way of obtaining an accurate estimate for this percentage? 1. Randomly select teenagers from the list of all teenage students in every state in America and mail surveys to those teens, asking them if they send or receive text messages while doing homework. 2. Send a survey to every teenager in America and ask them if they send or receive text messages while doing homework. 3. Randomly select teenagers from the list of all teenage students in one state and mail surveys to those teens, asking them if they send or receive text messages while doing homework.

There are 435 seats in a nation's House of Representatives. The number of representatives per state is calculated using a statistical formula determined by law, but allocation is roughly proportionate to population. In 2010, the nation's population was estimated to be 309.1 million. The state's population was estimated at 26.1 million. How many representatives would you expect to be assigned to the state? Suppose the state actually has 34 representatives. Compare this with the expected number of representatives from the state.

A restaurant chain would like to measure the proportion of customers who are generally satisfied with the service provided by its staff. At the end of the meal, as the check is delivered to the table, the server asks those at the table to rate their satisfaction with the service provided as "Very Satisfied," "Satisfied," or "Not Satisfied." During a one- week period, 147 customers were surveyed and 135 (93%) reported they were either Satisfied or Very Satisfied. How might the results be biased in obtaining an estimate of all customers who are satisfied with service? O Because of response bias, the survey results may overestimate the true proportion of satisfied customers. O Because of response bias, the survey results may underestimate the true proportion of satisfied customers. O Because of voluntary response bias, the survey results may overestimate the true proportion of satisfied customers. O Because customers were surveyed overa one-week period, the results should provide an…
