What could cause the development of longer legs to be selected over time? O A cause might be the decrease of rate of reproduction of the long-legged ponies O A cause might be that it made the long-legged ponies run more slowly O A cause might be that it prohibited the long-legged ponies from using available food resources O A cause might be the increase of survival rate of the long-legged ponies 4:29 PM 民 3/11/2021 O Type here to searchDr. I.M. Bright is studying whether digital or real life exhibits at the Greensboro Science Center are preferred by 8-year-old children. Specifically, she will examine whether participants spend more time at the digital animal exhibit or the real animal exhibit. In deciding how to divide children in her sample, she assigns the children who visit in the morning to the digital animal exhibit and the children who visit in the afternoon to the real animal exhibit. She records the amount of active engagement (i.e., time spent) by children at each exhibit. Dr. Bright found that children spent significantly more time in the digital animal exhibit as compared to the real exhibit and therefore concludes that 8-year-olds prefer digital exhibits. (1) Define the term “research confound.” Does Dr. Bright have any research confounds in her study (and if so, list them)? (2) Is Dr. Bright’s conclusion that 8-year-olds prefer digital exhibits valid? Explain with reference to the appropriate…What population and location would you like to complete placements with?

Please use source-supported facts to reinforce your opinion(s).Please help me answer An Egg Production Company recently found that eating eggs does not increase a person’s blood serum cholesterol. Five hundred subjects participated in a study that lasted for 2 years. The participants were randomly assigned to either no-egg group or a moderate-egg group. The blood serum cholesterol levels were checked at the beginning and end of the study. Overall, the groups’ levels were significantly different. The company reminds that eating egg is healthy if done in moderation. Many of the previous studies relating eggs and high blood serum cholesterol jumped to improper conclusion. Using this information, answer the following questions: What prompted the study? What is the population under study? Was a sample collected? What was the hypothesis? Were data collected? Were any statistical tests run? What was the conclusion?

- write a 150- to 200-word summary. Explain the legal or regulatory impact of the research study described in this article? Purpose: This study examined the relationship between cancer history and healthcare utilization among Asians residing in the United States. Methods: A cross-sectional analysis used 2011-2018 National Health and Nutrition Examination Survey data, focusing on the Asian demographic. Multiple logistic regression analyses evaluated the relationships between sociodemographic characteristics, cancer history, and healthcare utilization outcomes. These outcomes included self-rated health, healthcare usage during the previous year, overnight hospitalizations during the previous year, and the establishment of a routine healthcare facility. Results: A total of 2,956 Asian participants were included in our study. We found that cancer history significantly influences self-rated health, the frequency of healthcare visits, and the likelihood of overnight hospital stays. However, it…of Skill 3: Identifying Types of Data Sys Hypotheses are tested by evidence collected in the form of scientific data, or information obtained using specific analytical methods as part of an experiment or empirical observation. Scientific data can be qualitative or quantitative. Quantitative data are expressed as numeric values, rendering observations more objective and quantifiable, and can be either discrete of continuous. Discrete data can only take certain values (such as whole numbers), whereas continuous data can take any value mei within a range and can be represented by fractions and decimals. Qualitative, or categorical, data are descriptive, pertaining to properties that are difficult or impossible to express numerically, such as aspects of behavior or complex shape.
