A recent Gallup Poll asked 1523 adults if they bought a lottery ticket in the past year. Eight hundred sixty-eight (868) of the adults said "Yes." The poll was carried out by telephone, so people without phones were excluded from the sample. (a) Select the best answer to the question: Any errors in the final result due to excluding people without phones: A) Are included in the announced margin of error. B) Can be ignored, because these people are not part of the population. C) Are in addition to the announced margin of error. D) Can be ignored, because this is a nonsampling error. Selection: (b) The that is estimated in this survey is the proportionp of all adults who bought a lottery ticket. A) Mean B) Confidence interval C) Parameter D) Statistic

Suppose we want to estimate the proportion of the Helena population who have used marijuana within the last month. We select 4328 participants and ask them each to first privately draw a card from a standard 52-card deck. If they get a “club” they are asked to respond truthfully to the question “Have you used marijuana within the last month?”If they get any other suit they are asked to respond to the question “Does your phone number end in an odd digit?”The study is blinded in the sense that the researcher doesn’t know which question the participant is answering. Hence, participants are guaranteed anonymity and are more likely to be truthful in their responses. The researchers only get a “yes” or “no” answer from each respondent and don’t know the actual results of the card draw. What is the expected probability of a person’s phone number ending in an odd digit? What is the expected probability of a person’s phone number not ending in an odd digit?

A TV news reporter says that a proposed constitutional amendment is likely to win approval in the upcoming election because a poll of 541 likely voters indicated that 53% would vote in favor. The reporter goes on to say that the margin of error for this poll was 5%. Complete parts a and b below. a) Explain why the poll is actually inconclusive. Choose the correct answer below. O A. The poll is inconclusive because the standard error of the sample proportion is less than 0.50. O B. The poll is inconclusive because the margin of error is too large. OC. The poll is inconclusive because the sample size is too small. O D. The poll is inconclusive because 50% is included in the confidence interval. b) What confidence level did the pollsters use? The pollsters used a % confidence level.

1 The Blue Tide High School Student Committee has 5 members. They would like to conduct a survey to get the students’ opinion on the school’s new bell schedule. They asked 23 students’ representatives to distribute a questionnaire to the schools’ 1550 students. In the end, they received 750 responses. They wrote a report based on the information provided by the respondents. 2) which number represents the size of the sample?
A study considered the question, “Are you a registered voter?” Accuracy of response was confirmed by a check of city voting records. Two methods of survey were used: a face-to-face interview and a telephone interview. A random sample of 93 people were asked the voter registration question face-to-face. Seventy-nine respondents gave accurate answers. Another random sample of 83 people was asked the same question during a telephone interview. Seventy-four respondents gave accurate answers. Assume that the samples are representative of the general population. Test the claim that there is a difference in the proportion of accurate responses from face-to-face compared with telephone interviews. Use alpha=.05 What is the null hypothesis? What is the alternative hypothesis? What distribution are you using? What test are you running? What is your conclusion?

The Diversity, Equity, and Inclusion (DEI) office of a major multinational bank is investigating the process used to make recent hires for financial analysts. The office knows that exactly 10% of all applications were from minority candidates and that exactly 8% of the open positions were filled by members of a minority. For the investigation, the DEI office will take a random sample of 900 applications. Let p be the proportion of minority applicants in the sample. Answer the following. (If necessary, consult a list of formulas.) (a) Find the mean of p. 0 (b) Find the standard deviation of p. 0 (c) Compute an approximation for P(p ≤0.08), which is the probability that there will be fewer minority applicants in the sample than were hired by the bank. Round your answer to four decimal places. 0 X Ś
b) A certain pay television company wishes to estimate the proportion of its customers who would purchase a pay television program guide. To do this, the company manager decides to select a random sample of customers and note the number who would purchase a program guide. Suppose that experience in other areas suggests that about 13% of customers will purchase a program guide. How many customers should the company manager include in his sample if he wishes to estimate the true proportion who will purchase the program guide correct to within 5% (0.05) with a confidence level of 95%?
In a sample of 1000 randomly selected consumers who had opportunities to send in a rebate claim form after purchasing a product, 410 of these people said they never did so.
