Suppose that you are going to purchase ten grocery items, with prices: $[q].[qq], $[r].[rr], $[s].[ss], $[t].[tt], $[u].[uu], $[v].[vv], $[w].[ww], $[x].[xx], $[y].[yy], and $[z].[zz]. Estimate the total cost by rounding each item’s value to the nearest dollar and then computing a sum from those rounded amounts. Do not form your estimate in any other way. Input your you answer in whole dollars.

Use the bar graph to solve the next two problems. Estimate the yearly increase in average atmospheric concentration of carbon dioxide in parts per million (ppm). That is, compute

Consider the following conjecture: Multiplying both the numerator and denominator of a fraction by the same (nonzero) number never changes the fraction’s value. Is this conjecture true or false?

For her dissertation project, Wonjin examined the extent of relationships between neighborhood greenness and the psychological well-being of residents within the 77 neighborhoods of Chicago, IL. What is the independent variable in this study?

Please read the following scenario: Imagine a researcher named Olivia from an RST department. She studies risky leisure behaviors and hopes to learn about alcohol consumption among adolescents. To do this, she will study adolescents who have experienced binge drinking, their teachers, and/or their parents. Olivia’s supervisors are Professors Larson and Kim. These fictitious professors demonstrate two very different approaches to her study. Professor Larson believes that one strength of the research is that engages with people’s subjectivity and that Olivia should be transparent about her own subjectivity to enable readers to make judgments about it. Professor Larson advises Olivia that she will be recording and studying multiple perspectives, descriptions, interactions, and the dynamic way in which people bring issues and problems to life by talking about them or acting around them. Professor Kim’s beliefs are very different. He argues that Olivia’s proper task is to understand the reality of alcohol consumption among adolescents in a way that is as generalizable as possible. Professor Kim believes that Olivia can access participants’ real beliefs, attitudes, and knowledge: that Olivia can, for example, elucidate the essence of the experience of alcohol consumption or that she can determine what teenagers believe about drinking risks by measuring them. Professor Kim disagrees with Professor Larson’s position about subjectivity and transparency in research; in contrast, he strongly advises Olivia to avoid introducing bias and thus inaccuracy to her study. Please answer the following questions:  What are the philosophical worldviews that represent each professor’s beliefs? (2 points) Identify a worldview with which you are most comfortable as a researcher. Explain your reasoning and discuss if your worldview is aligned with your group’s research design (5 points). 

In 2020, you are trying to conduct research about COVID-19 and its impact on college students’ leisure behavior. Since less is known about COVID-19, there exists no previous literature or theories that had been used to explain this phenomenon. Eventually, you want to develop a model, or a theory based on the data you gathered. In this case which scientific research approach should you take?

Please read the following abstract: Latina women, a growing demographic in the United States, are largely absent from literature examining how race, ethnicity, and gender influence sport participation. This research explores how those factors intersect with socioeconomic status and generational status to influence how and when they joined organized sport, which sports they chose, and their perceptions of family support and belonging. Semi-structured interviews with 31 college-educated Latinas who played interscholastic high school sports in the US demonstrate that social class and nativity influence sport choices through habitus. Middle class and native-born families have resources to access organized sport and prioritize participation. Their daughters begin sport at an early age and are well-supported in their athletic careers. Lower-class and immigrant families place a lower value on organized sport and have fewer resources to access opportunities. Class and generation also intersect with gender, race, and ethnicity to influence when women join organized sports and how they make sense of their athletic participation.
