Trader Moe's is considering opening a Fayetteville location but their development office has learned that amain competitor, The Whole Market, currently has a store in development here. Trader Moe's conducts asurvey to see which store shoppers would choose if both were available within a 5 mile radius. Out of 200shoppers surveyed, 73 would go to Trader Moe's.Assunming the 95% confidence interval for those who would choose Trader Moe's. What would happen tothe confidence interval if a 99% confidence level were used?The interval would move to the right along the distributionIt would be narrower than the 95% confidence intervalThe interval would move to the left along the distributionIt would be wider than the 95% confidence interval

The security of two software systems are compared. A total of 225 security tests (fake attacks) were carried out on System 1 and, in 100 of them, the system was unaffected. On the other hand, 175 tests were conducted on System 2 and, in 40 of them, the system remained unaffected. Help test engineers decide whther there is a meaningful difference between the security levels of two systems (measured by the proportion of unsuccessful attacks) by building a confidence interval. Click here to view page 1 of the standard normal distribution table. Click here to view page 2 of the standard normal distribution table. With 99% confidence, the engineers can conclude that the difference among security levels p, - p2 will be between and (Round to three decimal places including any zeros.) Obviously, the interval V This means, the case p, - P2 = 0 excluded from 99% of all possible values p, - p2 can take. 0. P1 - P2- P2- P1 The security of two software systems are compared.

You may need to use the appropriate appendix table or technology to answer this question. A survey asked senior executives at large corporations their opinions about the economic outlook for the future. One question was, "Do you think that there will be an increase in the number of full-time employees at your company over the next 12 months?" In the current survey, 228 of 400 executives answered Yes, while in a previous year survey, 176 of 400 executives had answered Yes. Provide a 95% confidence interval estimate for the difference between the proportions at the two points in time. (Use current year previous year. Round your answer to four decimal places.) to What is your interpretation of the interval estimate? The 95% confidence interval ---Select--- ✓zero. This suggests that the proportion of executives who are predicting an increase in full- time jobs for the current year is ---Select--- ✓ than the proportion of executives who were predicting an increase in full-time jobs for the…
Suppose the English department of a local university has a total of 105 faculty members. Of this number, 24 (about 23%) are part-time instructors. Is it appropriate to find a confidence interval for the percentage of part-time instructors in the department? Find a 95% confidence interval or explain why you should not find a confidence interval for the percentage of part-time instructors in the English department.
What is meant by the term “90% confident” when constructing a confidence interval for a mean? If we took repeated samples, approximately 90% of the samples would produce the same confidence interval. If we took repeated samples, approximately 90% of the confidence intervals calculated from those samples would contain the sample mean. If we took repeated samples, approximately 90% of the confidence intervals calculated from those samples would contain the true value of the population mean. If we took repeated samples, the sample mean would equal the population mean in approximately 90% of the samples.

Two researchers, Jaime and Mariya, are each constructing confidence intervals for the proportion of a population who is lef-handed. They find the point estimate is 0.23. Each independently constructed a confidence interval based on the point estimate, but Jaime's interval has a lower bound of 0.220 and an upper bound of 0.234, while Mariya's interval has a lower bound of 0.169 and an upper bound of 0.272. Which interval is wrong? Why? 28 Choose the correct answer below. OA Jaime's interval is wrong because it does not include the point estimate. OB. Mariya's interval is wrong because it is too wide. OC. Mariya's interval is wrong because it is not centered on the point estimate, OD. Jaime's interval is wrong because it is to narrow O of 36
8.2 Question 3). According to the February 2008 Federal Trade Commission report on consumer fraud and identity theft, Arkansas had 1,601 complaints of identity theft out of 3,482 consumer complaints ("Consumer fraud and," 2008). Calculate a 90% confidence interval for the proportion of identity theft in Arkansas.
Suppose NBC has asked the same question to a sample of 1296 adults nine months earlier, finding 47% with an optimistic outlook for the year ahead. Develop a 95% confidence interval for the percentage of American adults who had an optimistic outlook for the economy nine months earlier.
