The Centers for Disease Control reported the percentage of people 18 years of age and older who smoke (CDCwebsite, December 14, 2014). Suppose that a study designed to collect new data on smokers andQuestions Navigation Menu inary estimate of the proportion who smoke of .26a. How large a sample should be taken to estimate the proportion of smokers in the population with a marginof error of .02 (to the nearest whole number)? Use 95% confidence.b. Assume that the study uses your sample size recommendation in part (a) and finds 520 smokers. What isthe point estimate of the proportion of smokers in the population (to 4 decimals)?c. What is the 95% confidence interval for the proportion of smokers in the population (to 4 decimals)?

You saw back in Chapter 2 that the mean, median, mode, and midrange are used to indicate where data is centered in a data set, or in other words what a typical value in the set is. A question that is often asked is, "If they're all supposed to do the same thing, why is there more than one?" Isn't one enough? In this exercise, you will be given two small sets of data. For each set, a. find the mean, median, mode and midrange b. in your opinion, decide which of the measures BEST represents all the values in the set (best indicates a typical value), and which one does this the WORST. c. post your responses and justify them by explaining why Don't forget to respond to at least one of your classmate's posts. With this exercise, "more is better." I'll elaborate after the deadline. • Set A: the salaries of 10 employees at a company (in thousands of dollars): 50, 50, 50, 50, 50, 50, 50, 50, 50, 500 • Set B: the grades of 9 students on an exam: 20, 25, 30, 35, 40, 45, 100, 100, 100
A study analyzed the sustainability behaviors of CPA corporations. The level of support for corporate sustainability (measured on a quantitative scale ranging from 0 to 160 points) was obtained for each in a sample of 984 senior managers at CPA firms. The CEO of a CPA firm claims that the true mean level of support for sustainability is 66. Complete parts a through e. What is a Type II error in this problem? A. A Type II error would be to conclude that the true mean level of support for sustainability is 66 when, in fact, the mean is not equal to 66. B. A Type II error would be to conclude that the sample mean level of support for sustainability is less than 66 when, in fact, the sample mean is greater than 66. C. A Type II error would be to conclude that the true mean level of support for sustainability is not 66 when, in fact, the mean is equal to 66. D. A Type II error would be to conclude that the sample mean level of support for…
Researchers want to estimate the percentage of people who thought drinking and driving was a serious problem. Reserchers waited outside a bar to question people. They usually find 11%of bar patrons believe drinking and driving is a serious problem. a. identify the populatin of interest b. identify the sample c. identify the population parameter of interest d. identifywho if anyone was left out of the study
An automobile repair shop reports that half of the automobiles they repair have a resale value below $ 4,000. In this example, the $4,000 represents which measure of central tendency? It is the mean O median mode range
You may need to use the appropriate appendix table or technology to answer this question. In a study entitled How Undergraduate Students Use Credit Cards, it was reported that undergraduate students have a mean credit card balance of $3,173. This figure was an all-time high and had increased 44% over the previous five years. Assume that a current study is being conducted to determine if it can be concluded that the mean credit card balance for undergraduate students has continued to increase compared to the original report. Based on previous studies, use a population standard deviation ? = $1,000. (a) State the null and alternative hypotheses. H0: ? < 3,173 Ha: ? ≥ 3,173 H0: ? = 3,173 Ha: ? ≠ 3,173 H0: ? > 3,173 Ha: ? ≤ 3,173 H0: ? ≥ 3,173 Ha: ? < 3,173 H0: ? ≤ 3,173 Ha: ? > 3,173 (b) What is the test statistic for a sample of 170 undergraduate students with a sample mean credit card balance of $3,305? (Round your answer to two decimal places.) What is…

Several studies showed that after eating a low-fat cereal for two meals a day, subjects had lost some weight.A cereal companyfinanced this research. Identify what is wrong. Choose the correct answer below. A. Since the research is composed of voluntary response samples, there may be key data points missing. B. The data used in the studies is not reliable because it was not measured by the administrator. C. It is questionable that the sponsor is a cereal company because this sponsor can be greatly affected by the conclusion. D. It is not possible to take accurate measurements.
Ms. Lorraine Finch, a fifth grade teacher has a large class of 50 students for the 2018 - 2019 school year. After giving a reading comprehension test, Ms. Finch decided to do a brief statistical analysis. A frequency distribution of the results is presented below. a. Fill in the missing pa rts of Ms. Finch’s frequency distribution. Do any necessary scrap work in the space next to the table. b. Construct a histogram of the frequency distribution. c Is the distribution of test scores normal? Explain.
