Select ant article, and provide a reference link so your article can be accessed. (any)Read the article and provide a summary of the article and any research done. 2-3 paragraphs will be sufficient. Look at the statistics used in the article. What was the research question (hypothesis)? What parameter would be of interest in this study (population mean, population proportion, population standard deviation, etc.) What was the statistical test run in the analysis? (Did they run a regression analysis, Z-test, T-test, ANOVA, etc.) Write 2-3 paragraphs on this. Reflect on why you chose the article and its applicability to nursing practice. I was helped with this but it was on my old account please help again.
When a correlational study demonstrates a relationship between two variables, it allows researchers to use knowledge about one variable to ______________ the second variable. Describe how the third-variable problem and the directionality problem limit the interpretation of results from correlational research designs and support that a correlational study may establish that two variables are related, it does not mean that there must be a direct relationship between the two variables.
Given, Hypothesis 1 is "The Suspect is the source of the bloodstain." and Hypothesis 2 is "The one-armed man is the source of the bloodstain.", and the Likelihood Ratio > 1, what is the appropriate conclusion? The one-armed man is the source of the bloodstain. Either the suspect or the one-armed man could be the source of the bloodstain. No conclusion can be made. The suspect is the source of the bloodstain.

The purpose of the experiment is to study how_____(IV) affects the _______(DV). Explain the background of the experiment and briefly describe the procedure. When explaining the background of the experiment, you are giving an overview of limiting factors. You should include evidence found in the background of information in the lab. Be sure to include examples of limiting factors, explain how limiting factors affect carrying capacity of a population. When describing the procedure be sure to include a summary of the steps used to gather the data.
A laboratory in British Columbia, the Kelatavicla lab, starts a mouse population where the frequency of the R allele is 0.5. You maintain this population for many years under the conditions found in column A. Given the information in the table (column A) and the information above it, predict what you think will happen to the frequency of the R allele. A) The frequency of the R allele will remain stable. B) The frequency of the R allele will increase. C) The frequency of the R allele will decrease.
What are some general tips in calculating allele and genotype frequencies? Examples of each will be useful.
A population of 1000 beetles has 600 individuals that have genotype QQ, 100 individuals that have genotype Qq, and 300 individuals that have genotype qq. a) Calculate f(Q) and f(q) for this population. Show your work and don’t assume HWE. b) Calculate f(QQ), f(Qq), and f(qq) for this population. Show your work and don’t assume HWE. c) Calculate the expected genotype frequencies if the population is in Hardy-Weinberg equilibrium. Show your work. d) Does this population appear to be at Hardy-Weinberg equilibrium? Why or why not? (Although answering this question rigorously would require a statistical test, you don’t need to do that here.).
In a population of 265 individuals, a locus has two alleles: E and e. If 59 individuals have the ee genotype, and the locus is at Hardy-Weinberg equilibrium, what is the frequency of the EE genotype?
The absolute fitnesses of the three genotypes in a two-allele system are given as follows: Genotype Absolute Fitness AA 0.08654 Aa 0.32143 aa 0.01662 What is the strength of selection against (i.e., the selection coefficient of) the Aa genotype? (Numerical answer; please do you all your work with at least 5 digits of precision)
A population is made up of individuals where 77 have the A1A1 genotype, 65 have the A1 A2 genotype, and 123 have the A2A2 genotype. What is the allele frequency of A1? Answer to 2 decimal places.
