A survey of 1363 Canadian students who enrolled in private career colleges was conducted to understand student participation in the private postsecondary education system. In one part of the survey, students were asked about their major source of funding. Here are thesurvey number of Canadian private students who use government loans, rely on funding from parents, family, or spouse, or use other sources of funding.Fields of Study Number of students use government loans Number of students rely on parents/family/spouse Other funding sources141232TradesDesign214140Media T10551165Other245Do Canadian private students' fields of study depend on their major source of funding?

Before books aimed at preschool children are marketed, reactions are obtained from a panel of preschool children. These reactions are categorized as favorable, neutral, or unfavorable. Subsequently, book sales are categorized as high, moderate, or low, according to the norms of this market. Similar panels have evaluated 1,000 books in the past. The accompanying table shows their reactions and the resulting market performance of the books. Panel Reaction Sales Favorable Neutral Unfavorable High Moderate Low 173 88 42 101 211 113 61 70 141 a. If the panel reaction is favorable, what is the probability that sales will be high?b. If the panel reaction is unfavorable, what is the probability that sales will be low?c. If the panel reaction is neutral or better, what is the probability that sales will be low?d. If sales are low, what is the probability that the panel reaction was neutral or better?
Background: Morris Saldov conducted a study in Eastern and Central Newfoundland in 1988 to examine public attitudes towards social spending. In particular, the study tried to determine if knowing someone on public assistance (yes, no) affected one's views on social spending (too little, about right, too much). The data from the study is summarized in the table below, Yes No Total Too little 39 8 47 About right 16 12 28 Too much 8 8 16 Total 63 28 91 Source: Morris Saldov, Public Attitudes to Social Spending in Newfoundland," Canadian Review of Social Policy, 26, November 1990, pages 10-14. Directions: Conduct a chi-square test for independence to determine if the association between knowing someone on public assistance and views on social spending is statistically significant. 1. Choose the correct null and alternative hypotheses. Ho: There is an association between knowing someone on public assistance and views on social spending.

Many countries, especially those in Europe, have significant gold holdings. But, many of these countries also have massive debts. The following data show the total value of gold holdings in billions of U.S. dollars and the debt as a percentage of the gross domestic product for nine countries (WordPress and Trading Economics websites, February 24, 2012). Country Gold Value Debt China 63 17.7 France 146 81.7 Germany 203 83.2 Indonesia 33 69.2 Italy 147 119 Netherlands 36 63.7 Russia 50 9.9 Switzerland 62 55 U.S. 487 93.2 c. Using the entire data set, develop the estimated regression equation that can be used to predict the debt of a country given the total value of its gold holdings. d. Use residual analysis to determine whether any outliers or influential observations are present. e. Suppose that after looking at the scatter diagram in part (a) that you were able to visually identify what appears to be an influential observation. Drop this observation…
The London School of Economics and the Harvard Business School have conducted studies of how chief executive officers (CEOS) spend their time. These studies have found that CEOs spend many hours per week in meetings, not including conference calls, business meals, and public events (The Wall Street Journal). Shown below is the time spent per week in meetings (hours) for a sample of 25 CEOS. 20 20 23 15 19 a. What is the least amount of time spent per week on meetings?

You will conduct a study of 100 people with cancer to better understand people's view the role of nutrition in their cancer diagnosis and treatment. This mixed methods study will include quantitative data collection from all 100 persons and qualitative data collection from about 20 persons. Your aims to to describe: o Describe sources of information about cancer-related nutrition (who did they learn cancer- related information from?) o Assess knowledge about cancer-related nutrition o Understand nutrition-related behaviors people changed due to their cancer diagnosis or treatment State which aims would best be measured with quantitative data and which aims would best be measured with qualitative data. Explain why you would use quantitative or qualitative data collection for each.
A study examined the interactions in a children's museum. (Interactions by visitors to the museum included show-and-tell, learning, teaching, refocusing, participatory play, advocating, and disciplining interactions.) Researchers observed a sample of 180 meaningful interactions, of which 86 were led by children and 94 were led by adult caregivers. Complete parts a through d below. a. Give a point estimate of the true proportion of all meaningful interactions in a children's museum that are led by children. The point estimate is. (Type an integer or decimal rounded to three decimal places as needed.)
Government economic studies reveal that young adults, not middle-aged or older adults, are having the most difficult time in today’s economy. Although the nation’s labor market shows a decline in the unemployment rate, the percentage of young adults, ages 18 to 24, currently employed (54 percent) is at the lowest level since the government data collection began in 1948. If you were working for a national survey organization doing a general public survey of young adults and older adults, what topics and questions would you design into your survey to elaborate on this finding?

Hospital administrators at a local hospital are interested in quality of care. As such, they ask a random sample of patients that have used the hospital's health care services to fill out a questionnaire. The questionnaire has questions about the patient's worry (negative, positive), the hospital staff's communication skills (low, medium, high), and satisfaction with medical care. The administrators are interested in how patient's worry and their assessment of the hospital staff's communication impact their satisfaction with medical care. The survey data are below. What can the administrators conclude with an α of 0.01? Communication Worry low med high negative 76868 54545 67495 positive 86677 78687 78666 A) Input the appropriate value(s) to make a decision about H0.Worry: p-value = Communication: p-value = Interaction: p-value = B) Using the SPSS results, compute the corresponding effect size(s) and indicate magnitude(s).Worry: η2 = Communication: η2 =…
