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.

2. According to the website Rotten Tomatoes, 94% of people who watched the Netflix show Stranger Things liked it. Since UR students tend to be scientifically minded, we hypothesize that less than 94% of UR students like the show. Out of 219 surveyed UR students, 198 indicated they like Stranger Things. Use the built in prop.test() function to: a. Construct a 90% confidence interval for the proportion of UR students who like Stranger Things. b. Test at the a=0.10 significance level whether the proportion of students who like Stranger Things is LESS THAN 0.94. What conclusion do you reach?
When you hold the mouse pointer over a point on the graph, the specific value corresponding to that point appears (e.g., “California, 2013 - 19.4%”) as well as a line called “90% Confidence” followed by an range of values. Generally speaking, what does the range of values denoted by “90% Confidence” indicate?
Find a 95% confidence interval for the percentage of stocks with a gain.
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.

If you are given summary statistics for a sample and want to construct a confidence interval, this can be done through the Probability Calculator in Geogebra, or Stat>Basic Stats>1-sample Z in Minitab(web). For Minitab (web), see Tutorials in D2L. For Geogebra, follow the directions below: Open it and click the "Statistics" tab just above the graph. For a confidence interval for a population mean, with unknown o, click the drop-down menu near the top (default is "Z Test of a Mean") and choose "T Estimate of a Mean." Enter the confidence level (in decimal form), sample mean, sample standard deviation, and sample size. We'll use a sample with = 65.17, s = 3.654, n = 26. Based on this sample data, a 95% confidence interval for the population mean is: <μ< The margin of error for this 95% confidence interval is Based on this sample data, a 99% confidence interval for the population mean is: <μ< The margin of error for this 99% confidence interval is -
Public Policy Polling recently conducted a survey asking adults across the U.S. about music preferences. When asked, 80 of the 571 participants admitted that they have illegally downloaded music.
