The comprehensive explanation of the proposed research is addressed to other specialists in your field. This includes: research design, setting and participants, data sources/instruments, data collection techniques, sampling techniques, analysis and interpretation, and ethical considerations. This section is the heart of the proposal and is the primary concern. Remember as you lay out the research design to: Be realistic about what can be accomplished. Be explicit about any assumptions or hypotheses the research method rests upon. Be clear about the focus of the research. Be as detailed as possible about the schedule of the proposed work. Be specific about the means of evaluating the data or the conclusions. Be certain that the connection between the research objectives and the research method is evident.56In which of these research designs would you have complete control of the environment?

- The GHQ is a well-known instrument for measuring minor psychological distress. The scale asks whether the respondent has experienced a particular symptom or behavior recently. Higher scores are associated with worst mental health. Past research has demonstrated that being of lower socioeconomic status was also associated with poorer mental health. The data are below: Participant Financial Security GHQ 1 20 25 2 18 23 3 18 17 4 19 35 5 19 18 6 18 24 7 19 24 8 14 25 9 10 27 10 7 50 i just need help on the blanks in the picture thankyouAspirin III: Decision and Conclusion Regarding the experiment in the data frame Aspirin from the abd package, the researchers wanted to know whether or not taking aspirin affects one's risk of developing cancer. Recall that they defined their parameters as follows: p1 = the proportion of ALL individuals who would develop cancer, if all of them were to take aspirin like the subjects in the Aspirin group did. p2 = the proportion of ALL individuals who would develop cancer, if all of them were to take a placebo, like the subjects in the placebo group did. They ran the code for a two-sided significance test and got the following results: ## ## ## Inferential Procedures for the Difference of Two Proportions p1-p2:## cancer grouped by treatment ## ## ## Descriptive Results:## ## yes n estimated.prop## Aspirin 1438 19934 0.07214## Placebo 1427 19942 0.07156## ## ## Inferential Results:## ## Estimate of p1-p2: 0.0005805 ## SE(p1.hat - p2.hat): 0.002586 ## ##…Which uses a group of people with different exposures and follows them over time?

Differences in education are a big factor in the "generation gap." Is the younger generation really better educated? Large surveys of people age 65 and older were taken in n1 = 38 U.S. cities. The sample mean for these cities showed that x1 = 15.2% of the older adults had attended college. Large surveys of young adults (age 25 - 34) were taken in n2 = 37 U.S. cities. The sample mean for these cities showed that x2 = 18.1% of the young adults had attended college. From previous studies, it is known that ?1 = 6.4% and ?2 = 4.8%. Does this information indicate that the population mean percentage of young adults who attended college is higher? Use ? = 0.05. (c) Find (or estimate) the P-value. (Round your answer to four decimal places.) A random sample of n1 = 12 winter days in Denver gave a sample mean pollution index x1 = 43. Previous studies show that ?1 = 15. For Englewood (a suburb of Denver), a random sample of n2 = 16 winter days gave a…

A physiologist, Dr. Castillejo, conducted a research wherein subjects participated in a predetermined exercise run of 1.5 miles. Measurements of oxygen consumption as well as several other variables such as age, gender, runtime, resting and maximum pulse rates, and weight were recorded from 50 randomly selected gym members. Dr. Castillejo is interested in determining whether any of these other variables can help predict oxygen consumption. She believes that a possible link between these factors will help her determine how to improve the health of her gym members. Help Dr. Castillejo in developing a proposal for the improvement of her gym members' health condition. The variables are described below. gender- either male or female runtime-time to run 1.5 miles (in min) age - age of the gym member in years weight-weight of the gym member (in kg) oxygen…
