Researchers asked parents of 19 American children, ages 8 to 12, to complete surveys on the number of hours their children spent reading and the number of hours they spent on screen-based media time. Each of the children also underwent magnetic resonance imaging (MRI) to assess connectivity in the brain. More time spent reading was associated with higher connectivity, while more screen time was associated with lower connectivity in the brains of the children. 1. What is the sample in this study? c 2. What is a possible population? F6 3. Is this an experiment or an observational study? Why did you make that decision? 4. Can we conclude that more time spent reading increases connectivity in children's brains? 5. Identify a possible confounding variable and explain how it meets the definition of a confounding variable. MacBook Air tv♫ F7 * 2 DII F8 ( ZA F9 1 F10 & F11 DOCX A
You have been asked to estimate the proportion of households in Chicago that have two or more vehicles. a) How many households would you need to sample to be within 2 percent of the proportion of all households in Chicago that have two or more vehicles at a 90% level of confidence. b) You conduct a small preliminary sample, and you obtain a sample proportion of 19.5% that have two or more cars. Using this new information, what sample size should you gather in order to be within 2 percent of the proportion of all households in Chicago that have two or more vehicles at a 90% level of confidence.

Sociologists argued that women on average earn less than men as women often choose to work less hours. They further suggest that the choice of hours worked may be driven by various factors such as age, childcare needs, occupation choice and flexibility. To investigate the relation between hours worked and income earned by Australian men and women, a researcher plans to survey a sample of individuals across the country. Briefly explain a) What type of survey method the researcher could use and why? b) What sampling method could the researcher use to select his/her sample and why? c) What are the two main variables the researcher should consider collecting data for the purpose of the above analysis and why? Identify the data type(s) for the variables. d) What kind of issues the researcher may face in this data collection? Suppose a researcher has collected data from a sample of 65 individuals using the sampling method you have proposed in (b). For each individual, the hours worked per…
