15. Sampling consumer data may be your only option dueto time and cost constraints. Yet that will lead to "samplingerror", thus we do "confidence intervals" to lay out ourcertainty levels of our data findings. Please calculate aconfidence interval for the percent of your customers youexpect to go unsatisfied. You surveyed 76 customers andfound that 22% of them were unsatisfied. You wish to be93% confident when stating this interval range. Thepopulation of customer data is 600 surveys. Round youranswers to the thousandth place. Hint: FPCF?

A sociologist wishes to conduct a poll to estimate the percentage of Americans who favor affirmative action programs for women and minorities for admission to college and universities. She wants to use a 2003 estimate of 55% obtained from a Gallup Youth Survey as a prior estimate. What sample size should be obtained if she wishes the estimate to be within 4 percentage points with 90% confidence?
Suppose we want to estimate the proportion of college students who use stimulants to help them study. If we want to estimate this proportion to within 5% at the 95% confidence level, how many randomly selected college students must we survey?If we want to estimate this proportion to within 5% at the 90% confidence level, do we need to survey more students or can we survey fewer students (compared to your previous answer)? We need to survey more students or We can survey fewer students If we want to estimate this proportion to within 4% at the 95% confidence level, do we need to survey more students or can we survey fewer students (compared to your first answer)? We need to survey more students or We can survey fewer students
A television sports commentator wants to estimate the proportion of citizens who follow professional football. What sample size should be obtained if he wants to be within 4 percentage points with 96% confidence, if he uses an estimate of 54% obtained from a poll? What sample size should be obtained if he wants to be within 4 percentage points with 96% confidence if he does not use any prior estimates? Why are the results so close?
Researchers wanted to conduct a study on the GPA of third year working engineering students in their University. They think that some students with work learned how to manage their time wisely and step up to leadership challenges, while a certain portion of them have problems balancing work and school, and thus, experience stress more than non-working students. The study wants to identify if there is significant difference on the GPA of third year working students with leadership roles and working students without. Identify the population from which the study should be sampled. a. All working students b. Third year working engineering students c. All engineering students in the University d. Third year Engineering Students with part-time job who have adequate time-management and leadership skills.
. A school psychologist wants to test the effectiveness of a new method for teaching reading. She takes 500 first grade students from District 12 (all with the same teacher), and randomly assigns half of them to the traditional method and half of them to the new method for teaching reading. The students are not told which teaching method they are being taught with. At the end of the year, she obtains all scores on a reading achievement test, and looks for any differences between the two groups. a. What is the research objective? b. What type of study was used? Give the exact name. c. Does this study make use of random sampling, random assignment, both, or neither? How do you know? d. What are the explanatory and response variables? Explanatory Variable: Response Variable: e. What are the treatments? e. Was blinding used? If so, how?
Prof. Juan believes that one of the greatest challenges of remote teaching is ensuring that students can self-direct their learning. Prof. Juan would like to know if majority of his students carry out their own study plan. Although Prof. Juan was able to provide a calendar of tasks, he thinks that there must be some other way to encourage his students to learn more independently. From the sample of 50 students, the estimated proportion of students who carry out their own study plan is 0.56 or 56% . In addition, there is 95% confidence that it is between 0.4125441 or 41.25% and 0.7000928 or 70.01%. Using the binomial exact test with a p-value equal to 0.2399, it can be said that there is _______ evidence that the proportion of students who carry out their own study plan is ____________Therefore, __________ of the students are able to self-direct their learning. On a side note, the large sample assumption of the approximate Z-test was ____________since _______________ Hence,…
Suppose that, for budget planning purposes, the city in the previous exercise needs a better estimate of the mean daily income from parking fees. a) Someone suggests that the city use its data to create a 95% confidence interval instead of the 90% interval first created. How would this interval be better for the city? (You need not actually create the new interval.) b) How would the 95% interval be worse for the planners? c) How could they achieve an interval estimate that would better serve their planning needs?
How can someone recognize when an inferential statistics problem involves either a confidence interval estimate or a hypothesis testing procedure and when it involves either a mean or a proportion?

A nationwide job recruiting firm wants to compare the annual incomes for childcare workers in Texas and Indiana. Due to recent trends in the childcare industry, the firm suspects that the mean annual income of childcare workers in Texas is less than the mean annual income of childcare workers in Indiana. To see if this is true, the firm selected a random sample of 20 childcare workers from Texas and an independent random sample of 20 childcare workers from Indiana and asked them to report their mean annual income. The data obtained were as follows. Annual income in dollars Texas 37093 , 33960 , 35692 , 29528 , 30978 , 35504 , 26961 , 28380 , 37537 , 25341 , 34837 , 36489 , 33633 , 41229 , 43577 , 27644 , 43364 , 28415 , 28919 , 34096 Indiana 33672 , 46452 , 35900 , 28486 , 46528 , 34252 , 40952 , 42164 , 36298 , 38828 , 32690 , 29157 , 42770 , 35527 , 40804 ,…
In country A, the vast majority (90%) of companies in the chemical industry are ISO 14001 certified. The ISO 14001 is an international standard for environmental management systems. An environmental group wished to estimate the percentage of country B's chemical companies that are ISO 14001 certified. Of the 550 chemical companies sampled, 396 are certified. a) What proportion of the sample reported being certified? b) Create a 95% confidence interval for the proportion of country B's chemical companies with ISO 14001 certification. (Be sure to check conditions.) Compare to the country A proportion.
In 2013 students from a Statistics class at FSEV UK were asked to survey their friends who were 15-30 years old, in order to explore the interests of young people. The survey has a variety of questions, which are detailed in the Survey Key. For example, the column header “Music” is short for the question “I enjoy listening to music” and is rated 1-5, where 1 represents strongly disagree and 5 represents strongly agree. There is also some categorical data present as well. Survey participants record their gender, how often they smoke/drink, their internet usage, and education (just to name a few!). Please perform a hypothesis test based on one of the categorical variables and one survey question. For example, you could choose to prove the following: Survey participants who identify as an “only child” enjoy meeting new people (Survey score ). Here is an example: people who are right-handed (as identified in the data set) enjoy listening to music. Please be sure to use two columns…
