A political poll of Americans was conducted to investigate their opinions on gun control.Each person was asked if they were in favor of gun control or not in favor of gun control,or I am not sure. The survey found that 25% of people contacted were not in favor ofgun control laws. These results were accurate to within 3 percentage points, with 95%confidence. Which of the following is NOT correct?a. The 95% confidence interval is approximately from 22% to 28%b. We are 95% confident that the true proportion of people not in favor of gun controlIis within 3 percentage points of 25%C. In approximately 95% polls on this issue, the confidence interval will include thesample proportion.d. If another poll of similar size were taken, the percentage of people IN FAVOR of guncontrol would likely range from 72% to 78%10,294APR1030atv AAaMacBook ProDIIDD20000D00F9F10F11F12F5F6F7F8F2F3F4

Suppose you find that the 95% confidence interval for the cost of a wedding is ($29,000, $35,000). What is the correct interpretation of this interval? Group of answer choices For the next wedding you attend, the cost will be between $29,000 and $35,000. There is a 95% probability that the sample mean is between $29,000 and $35,000. There is a 95% probability that the population mean is between $29,000 and $35,000. You are 95% confident that the mean wedding cost is between $29,000 and $35,000. thanks
Mental health. The General Social Survey asked the question: “For how many days during the past30 days was your mental health, which includes stress, depression, and problems with emotions, not good?”Based on responses from 1,151 US residents, the survey reported a 95% confidence interval of 3.40 to 4.24days in 2010.(a) Interpret this interval in context of the data.(b) What does “95% confident” mean? Explain in the context of the application.(c) Suppose the researchers think a 99% confidence level would be more appropriate for this interval. Willthis new interval be smaller or wider than the 95% confidence interval?(d) If a new survey were to be done with 500 Americans, do you think the standard error of the estimatebe larger, smaller, or about the same.
Eric randomly surveyed 150 adults from a certain city and asked which team in a contest they were rooting for, either North High School or South High School. From the results of his survey, Eric obtained the following 95% confidence interval for the proportion of all adults in the city rooting for North High, (0.52,0.68). Interpret this confidence interval. A.We are 95% sure that between 52% and 68% of all adults in this city will root for North High School.B.We are 95% sure that between 52% and 68% of adults in this sample will root for North High School.C.There's a 95% chance that between 52% and 98% of all adults in this city will root for North High School.D.Between 52% and 68% of adults in this city will root for North High School 95% of the time.

A college professor would like to estimate the proportion of students who pull an "all-nighter," meaning they study all night for an upcoming exam. She selects a random sample of 100 students from her large college and finds that the 99% confidence interval for the true proportion of students who pull an all-nighter is 0.48 to 0.62. Which of these statements is a correct interpretation of the confidence level? O Approximately 99% of all students have pulled an all-nighter. O There is a 99% probability that the true proportion of all students who pull an all-nighter is between 0.48 and 0.62. If many random samples of size 100 are selected from all students at this college, approximately 99% of the intervals would capture the true proportion who pull an all-nighter. C Approximately 99% of the sample proportions of students who pull an all-nighter, based on random samples of size 100 from the population of all students at this college, will fall between 0.48 and 0.62.

A poll was conducted to determine why Americans decide not to go to college. Of the 335 Americans who didn't go to college survey surveyed, 47% decided not to go to college because they couldn't afford it. Suppose we wanted the margin of error for the 90% confidence level to be about 1.5%. What sample size would you recommend for the survey? Round your answer appropriately.
Siblings Mary and David are each attempting to estimate the proportion of families in their neighborhood who have five or more children. Mary selects a random sample of 50 families to survey, and she observes a sample proportion of 0.10. David selects a random sample of 100 families to survey, and he also observes a sample proportion of 0.10. Mary and David each use their sample data to construct a 95% confidence interval. Who will have the more narrow confidence interval? A. Both intervals will have the same width since the sample proportions are the same. B. Both intervals will have the same width since the level of confidence is the same for each interval. C. Both intervals will have the same width since the sample proportions are the same and the level of confidence is the same for each interval. D. Mary's interval will be more narrow than David's interval. E. David's interval will be more narrow than Mary's interval.
